This document is intended to be a reference manual for Apache Axis2/C. This manual details how Axis2/C can be used to provide and consume Web services.
Please send your feedback to the Apache Axis2/C developer mailing list (c-dev@axis.apache.org). Subscription details are available on the Apache Axis2/C website.
This document uses the following conventions:
This section is aimed to help you get a Web service running in a short time using Axis2/C, and consume that service using an Axis2/C client.
First, download the latest binary release from Apache Axis2/C. Once you download the correct binary that suits your platform, all that you require to get it running is to extract the package to a folder of your choice, and set the AXIS2C_HOME environment variable to point to this extracted folder. For Linux, you may have to set the LD_LIBRARY_PATH environment variable to include the lib folder (e.g. add $AXIS2C_HOME/lib). For MS Windows, you will have to add the lib folder to your PATH variable to include the Axis2/C DLLs to your path.
Now you should be able to change the directory to the bin folder of the extracted folder, and run the simple axis server in one command shell. Then change the directory to samples/bin in another command shell and run any of the samples there (you may have to set the environment variables in this new shell as well). Please see the installation guide for more details.
Once you have Axis2/C up and running successfully, you can start writing your own services and clients. The following sections explain how to write your first service and client with Axis2/C.
Let's see how you can write your first Web service with Axis2/C and how to deploy it.
The first service that we are going to write is named "hello" with a single operation named "greet" in the service. This "greet" operation, when invoked by the client, will expect the client to send a greeting in the request, and in turn send a greeting in the response. Following are examples of XML payloads exchanged between the client and the service:
Request:
<greet>
Hello Service!
<greet>
Response:
<greetResponse>
Hello Client!
<greetResponse>
The steps to be followed when implementing a service with Axis2/C include:
axis2_hello_greet
.axis2_svc_skeleton
interfaceaxis2_svc_skeleton
interface expects the
functions init
, invoke
,
on_fault
and free
to be implemented by our service.hello_init
,
hello_invoke
, hello_on_fault
and hello_free
respectively.Look for the axis2_hello_greet
function in the hello_svc.c
source file.
This function implements the business logic for the greet
operation. We
will be calling this function from our implementation of the invoke
function.
Basically, this function receives the request payload as an
axiom_node
, process it to understand the
request logic, and
prepares the response as an axiom_node
and
returns that.
Look for the axis2_hello_create
function in the hello_svc.c
source file.
The create function creates and returns a new
axis2_svc_skeleton
instance. The most
important aspect to note
about this function is the function pointer assignments. They are used
to map
the interface operations to the corresponding functions of the
implementation. This is done by assigning the ops member of the service
skeleton to the address of the ops struct variable.
The invoke method of the service skeleton is the point of entry for invoking the operations. Hence in our implementation of the invoke function, we have to define how the operations are to be called.
Look for the hello_invoke
function
in the hello_svc.c
source file.
In our implementation of the hello_invoke
,
we call the
function implementing the greet operation. As we have only one
operation, the
task is simple here. If we had multiple operations, we will have to
look into
the information in the message context to map it to the exact
operation.
The Axis2/C engine will call the invoke method with an
axiom_node
, containing the request payload,
and
axis2_msg_ctx
instance, containing the message
context
information, in addition to the service skeleton and the environment
pointers. We can use the message context to extract whatever
information we
deem necessary that is related to the incoming message. The Axis2/C
engine
expects the invoke method to return a pointer to an axiom_node
,
representing the response payload.
The services.xml file contains details on the service that would be read by the Axis2/C deployment engine during server start up time. The following shows the contents for the services.xml file for the hello service.
<service name="hello">
<parameter name="ServiceClass" locked="xsd:false">hello</parameter>
<description>
Quick start guide hello service sample.
</description>
<operation name="greet"/>
</service>
The service configuration shown above specifies that the name
of the
service is hello.
The value of the "ServiceClass", "hello" in this case, will be mapped
to the
service implementation by the deployment engine as libhello.so on Linux
or
hello.dll on MS Windows. The description element contains a brief
description
of the service.
There can be one or more operation elements. For this sample, we only
have
one operation, with the name "greet".
You can compile the service sample as shown below.
On Linux:
gcc -shared -olibhello.so -I$AXIS2C_HOME/include/axis2-1.6.0/ -L$AXIS2C_HOME/lib -laxutil -laxis2_axiom -laxis2_parser -laxis2_engine -lpthread -laxis2_http_sender -laxis2_http_receiver hello_svc.c
On MS Windows:
to compile,
cl.exe /D "WIN32" /D "_WINDOWS" /D "_MBCS" /D "AXIS2_DECLARE_EXPORT" /D "AXIS2_SVR_MULTI_THREADED" /w /nologo /I %AXIS2C_HOME%\include /c hello_svc.c
to link,
link.exe /nologo /LIBPATH:%AXIS2C_HOME%\lib axutil.lib axiom.lib axis2_parser.lib axis2_engine.lib /DLL /OUT:hello.dll *.obj
To make the service available to be consumed by the clients, we have to deploy the service. To deploy the service, you have to create a folder named 'hello' in the AXIS2C_HOME/services folder, and copy the services.xml file and the shared library file (libhello.so on Linux or hello.dll on MS Windows) into that folder.
To verify that your service has been correctly deployed, you can start the simple axis server and then browse the list of deployed services using a Web browser. To start the simple axis server, you can go to the AXIS2C_HOME/bin folder and run the executable axis2_http_server. The default URL that you can test the service list with is http://localhost:9090/axis2/services. You should get an entry for the hello service on the page that is displayed.
Axis2/C does not support dynamic WSDL generation. However, it is possible to attach the contract you used to generate the service skeleton, to the respective service. This can be done in two ways.
If you choose the first option, you will have to copy the WSDL
file to the folder in which the service DLL is found. The name of the
WSDL file should be the name of the service. And, if you choose the
second option, you will have to make use of the wsdl_path
parameter in the services.xml file. More info on how this can be done
is found under the services.xml
section.
An example of the second option can be found the services.xml of the echo sample service, which is commented. An example of the first option in use is seen in the Calculator sample service.
The static WSDL file can be accessed by appending ?wsdl
to the service end-point. You can view the WSDL provided for the
Calculator sample, by pointing to http://localhost:9090/axis2/services/Calculator?wsdl.
Now that you know how to write a service with Axis2/C, let's see how to write a client to consume that service. The request payload that the client will be sending to the service was described in the previous section. The client has to prepare the payload, send it to the service, and then receive and process the response.
The steps to be followed when implementing a client with Axis2/C:
axutil_env_create_all
method can be used to create a default, ready to use environment
instance. axis2_options
struct can be used to set
the client side options. For example, we can use options to set the
endpoint address of the service to be consumed by the client. axis2_svc_client
struct is meant to be
used by the users to consume Web services. It provides an easy to use
API. Service client create method takes the location of the repository
as a parameter. For the purpose of our sample, you can use the
AXIS2C_HOME as the repository. The concept of repository
is explained in detail in a later section.axis2_svc_client_send_receive
method can be used to invoke the send receive operation on the service
client instance.axiom_node
and returns the response payload as an axiom_node
.options = axis2_options_create(env);
address = "http://localhost:9090/axis2/services/hello";
endpoint_ref = axis2_endpoint_ref_create(env, address);
axis2_options_set_to(options, env, endpoint_ref);
In the above section of code, an axis2_options
instance is
created first. Then an endpoint reference instance is created with the
address of the location of the service. Finally, the created endpoint
is set
as the "to" address of the options. The "to" address indicates where
the
request should be sent to.
svc_client = axis2_svc_client_create(env, client_home);
axis2_svc_client_set_options(svc_client, env, options);
payload = build_om_request(env);
ret_node = axis2_svc_client_send_receive(svc_client, env, payload);
After creating and preparing the options, the next step is to
create a
service client instance and use it to send the request and receive the
response. The code fragment given above shows how options can be set on
top
of the service client and how to invoke the send receive operation with
a
request payload. Once the response is received, the response payload
will be
stored in the ret_node
, which is a pointer to
an
axiom_node
that can be used to process the
response further.
You can compile the client sample as shown below.
On Linux:
gcc -o hello -I$AXIS2C_HOME/include/axis2-1.6.0/ -L$AXIS2C_HOME/lib -laxutil -laxis2_axiom -laxis2_parser -laxis2_engine -lpthread -laxis2_http_sender -laxis2_http_receiver hello.c -ldl -Wl,--rpath -Wl,$AXIS2C_HOME/lib
On MS Windows:
to compile,
cl.exe /nologo /D "WIN32" /D "_WINDOWS" /D "_MBCS" /I %AXIS2C_HOME%\include /c hello.c
to link,
link.exe /LIBPATH:%AXIS2C_HOME%\lib axutil.lib axiom.lib axis2_parser.lib axis2_engine.lib /OUT:hello.exe *.obj
Repository is a folder where all Axis2/C related configurations as well as services and modules are located. The following shows the folder structure of the repository:
Here the name of the repository folder is axis2c_repo. In your system, you can specify any folder name of your choice. There are three sub folders available in the repository. In addition to that, the axis2.xml configuration file is also located in the repository. The following table describes the purpose of the repository contents.
Folder/File Name | Description |
---|---|
lib |
The lib folder contains the libraries required to run
the Axis2/C engine. While you can afford to have the shared libs of
Axis2/C in a location of your choice, the dynamically loaded shared
libs, parser, transport receiver and transport sender has to be in the
repository lib folder. |
modules [optional] |
The modules folder contains the modules deployed with
Axis2/C. Each module deployed will have its own sub folder inside the
modules folder. For example, if the addressing module is deployed, then
there will be a sub folder named addressing inside the modules folder
of the repository. |
services [optional] |
The services folder contains the services deployed with
Axis2/C. Each service deployed will have its own sub folder inside the
services folder, or live inside one of the sub folders. |
axis2.xml |
The axis2.xml file is the configuration file of Axis2/C. |
Both clients as well as the services written using Axis2/C can use the same repository. However you can use one repository for the server side and another one for the client side. The services folder is used only when the repository is used by the server side. When the repository is used by the client, the services folder, if present, will not be used.
The Axis2/C binary distribution, when extracted, can be considered as ready for use as your repository folder. If you are building Axis2/C from the source distribution, when you build the source, including the samples, the installation destination will be ready for use as your repository folder.
The simple axis server (that is axis2_http_server binary), the client samples, and the HTTPD module (Axis2 Apache2 module) require the repository folder to be specified in order to run correctly.
As described earlier, all the modules are placed inside the
modules folder
of the repository, and each module will have its own sub folder within
the
modules folder.
The folder in which a module is placed must have the same name as the
module
name. For example, the addressing module will be placed in a sub folder
named
addressing.
Inside the folder corresponding to a module, the shared library implementing the module and the module configuration file, module.xml, is placed. It is a must that these two files are present inside each folder representing a module. The module.xml file will be processed by the deployment engine to find out module specific information such as the module name, set of handlers, the flows into which those handlers are to be added, etc.
All the services are placed inside the services folder of the repository, and each service will be in one of the sub folders within the services folder. Axis2/C has a concept called service groups, where there can be one or more services inside a service group. A single stand alone service is assigned a service group with the same name as that of the service by the Axis2/C engine for the purpose of easy handling. Therefore the sub folders in the services folder correspond to the service groups.
A service, if deployed as a stand alone service, will reside inside a folder with the same name as that of the service. For example, the echo service will be placed in a sub folder named echo. The shared library implementing the service and the service configuration file, the services.xml, will be placed inside the folder corresponding to a service. Given the fact that the engine treats the folders to represent service groups and not a single service, the configuration file is called services.xml. However, you can always place a single service inside a single folder, which is the most common use case.
Each sub folder within the services folder should have at least one shared lib implementing a service and a services.xml file. If it is a real service group, there will be multiple shared libs, yet there is only one services.xml file configuring all those services. The services.xml file is processed by the deployment engine to find out the service group and the service specific information such as the service group name, service name, the set of operations for each service, etc.
We have already seen how to write a service in the Quick Start Guide section of this manual. This section covers the service API of Axis2/C in more detail.
axis2_svc_skeleton
is an interface.
Axis2/C does not provide
any concrete implementation of this interface. It is the responsibility
of
the service implementer to implement this interface. To implement the
interface, you should implement the functions adhering to the function
pointer signatures of the members of the axis2_svc_skeleton_ops
struct. Then, a create function should be written to create an
axis2_svc_skeleton
instance, and assign the
implementing
functions to the members of the ops member of service skeleton.
The following table details the signatures of the function
pointer members
of the axis2_svc_skeleton
struct implemented
by a service.
Function Signature | Description |
---|---|
int (AXIS2_CALL * | Initializes the service skeleton object instance. The Axis2/C engine initializes a service skeleton instance once per deployed service, during the first request made to the service. |
axiom_node_t *(AXIS2_CALL* | Invokes the service implementation. You have to implement the logic to call the correct functions in this method based on the name of the operation being invoked. |
axiom_node_t *(AXIS2_CALL* | This method is called by the engine if a fault is detected. |
axis2_status_t (AXIS2_CALL * | Frees the service implementation instance. |
There are two more methods that a service should implement.
Once a service
is deployed, the message receiver of the Axis2/C engine has to create a
service instance at run time for the purpose of invoking it. For this,
it
looks for a method named axis2_create_instance
and calls it on
the service shared library. The engine also looks for a function named
axis2_remove_instance
in the shared library
for clean up
purposes.
Function Signature | Description |
---|---|
AXIS2_EXPORT int | Creates an instance of the service. You have to implement the logic of creating the service object, allocating memory etc. in this method. |
AXIS2_EXPORT int | Removes the instance of the service. Do any cleaning-up and deallocations here. |
Note that service object instantiation happens once per service. When the first request is received by the service, a service skeleton instance is created and initialized. The same object instance will be re-used by the subsequent requests.
You can find an example on how to implement the service skeleton interface in the hello_svc.c source file, which is the example used in the Quick Start Guide. More advanced samples can be found in the samples folder of the Axis2/C distribution.
The primary client API to be used with Axis2/C is
axis2_svc_client
, the service client API. This
is meant to be an
easy to use API for consuming services. If you want to do more complex
tasks,
such as invoking a client inside a module, or wrap the client API with
another interface, you may need to use axis2_op_client
,
the
operation client API. For most of the use cases, the service client API
is
sufficient.
The behavior of the service client can be fine tuned with the
options
passed to the service client. You can set the options by creating an
axis2_options
instance. The bare minimum that
you need to set is
the endpoint URI to which the request is to be sent. An example of this
was
given in the Quick Start Guide
section.
The service client interface serves as the primary client interface for consuming services. You can set the options to be used by the service client and then invoke an operation on a given service. There are several ways of invoking a service operation. The method of invoking an operation depends on 3 things. They are,
Many service operation invocation scenarios can be obtained by combining the above three factors. The service client interface provides the necessary API calls to achieve this.
Deciding the Message Exchange Pattern (MEP)
There are 2 message exchange patterns.
In the Out-Only MEP, the client doesn't expect a reply from the server. The service client provides two methods of using the Out-Only MEP.
Function Signature | Description |
---|---|
AXIS2_EXTERN void AXIS2_CALL | Sends a message and forgets about it. This method is used to interact with a service operation whose MEP is In-Only. There is no way of getting an error from the service using this method. However, you may still get client-side errors, such as host unknown. |
AXIS2_EXTERN axis2_status_t AXIS2_CALL | This method too is used to interact with a service
operation whose MEP is In-Only. However, unlike axis2_svc_client_fire_and_forget ,
this function reports an error back to the caller if a fault triggers
on the server side.When using Out-In MEP, the client expects a reply from the server. axis2_svc_client_send_receive
and axis2_svc_client_send_receive_non_blocking functions
support this MEP |
AXIS2_EXTERN axiom_node_t *AXIS2_CALL | This method is used to interact with a service
operation whose MEP is In-Out. It sends an XML request and receives an
XML response. Returns a pointer to the AXIOM node representing the XML response. This method blocks the client until the response arrives. |
AXIS2_EXTERN void AXIS2_CALL | This method too, is used to interact with a service
operation whose MEP is In-Out. It sends an XML request and receives an
XML response, but the client does not block for the response. In this method, the client does not block for the response, but instead it expects the user to set a call back to capture the response. |
Please have a look at the axis2_svc_client.h
header file for
more information on the above mentioned functions, as well as their
synonyms
that accept an operation's qualified name.
This will determine whether the client would block for the
response
(synchronous) or return immediately expecting the response to be
handled by a
callback (asynchronous, in other words non-blocking) in an Out-In MEP
scenario.
axis2_svc_client_send_receive
operates in
synchronous mode,
whereas axis2_svc_client_send_receive_non_blocking
operates in
asynchronous mode.
If the transport is two-way, then only one channel is used,
which means
the request is sent and the response is received on the same channel.
If the
transport is one-way, then the request is sent on one channel and the
response is received on a separate channel.
If we want to use a separate channel for the response, a separate
listener
has to be started to receive the response, This can be done by setting
the
separate listener option to True using the
axis2_options_set_use_separate_listener
function above the
options.
Please have a look at the echo_blocking_dual
sample to see
how to set the separate channel option.
Please see Appendix D for further details on setting options.
Axis2/C comes with plain old XML (POX) like REST support. A
given service
can be exposed both as a SOAP service as well as a REST service. By
default,
your service will support SOAP as well as REST, however, your service
operations
will only be available for SOAP. In order to enable REST for your
operations you
need to add one or more parameters under your operation, in the services.xml.
If you want to consume Web services using REST style calls, you can use
the HTTP
POST method, the HTTP GET method, the HTTP HEAD method, the HTTP PUT
method or
the HTTP DELETE method.
The following example code fragment shows how to set up a client enabling a REST style invocation.
axis2_options_set_enable_rest(options, env, AXIS2_TRUE);
You can use the same code that you use with a SOAP call, and do REST style invocation by just enabling REST using the option setting shown above.
The default HTTP method used with REST is HTTP POST. If you need to change it to the HTTP GET method, the following needs to be done.
axis2_options_set_http_method(options, env, AXIS2_HTTP_GET);
Similarly you can use AXIX2_HTTP_HEAD to change it to the HTTP HEAD method, or AXIX2_HTTP_PUT to change it to the HTTP PUT method, or AXIX2_HTTP_DELETE to change it to the HTTP DELETE method.
Please have a look at the echo_rest
sample for a complete
source code on how to use REST.
You basically need to add the REST Location, and the REST
Method parameters to the services.xml
to enable REST in a service operation. The REST location is the
template that needs to be matched
to find your operation, and the REST Method is the HTTP Method
associated with the service.
Note that the REST Method is optional for each operation. If no REST
Method is specified, POST,
will be assumed. Optionally you may specify the default REST Method for
all operations at the service
level. Then, if you haven't specified a REST Method for your operation,
the default REST Method
specified will be assumed instead of POST. Please have a look at the echo
sample
service for a complete source code on how to set up REST. Shown below
is an example, on how to
configure the locate
operation to work with
HTTP GET on REST.
<operation name="locate">
<parameter name="RESTMethod">GET</parameter>
<parameter name="RESTLocation">location/{lat}/{long}</parameter>
</operation>
The corresponding request would look like, http://www.sample.org/service/location/34N/118W
,
which would return Los Angeles, California. In here, the portion location
is fixed and lat
and long
are optional parameters which will be captured to the payload.
It is also possible to enable a single service operation for
SOAP as well as REST. This can be done by specifying a REST Location
that does not contain the operation name. The locate
operation is an example to such a case. Thus, for a SOAP invocation,
you need to use http://www.sample.org/service/locate
,
as the end point or WS-Addressing Action.
Axis2/C allows you to send and receive binary data with SOAP
messages
using MTOM/XOP conventions. When sending and receiving attachments, you
have
to use the service client (axis2_svc_client
)
API to perform the
send and receive operations, and provide or consume binary data in
relation
to the AXIOM payloads.
In order to send a binary attachment, you need to build the AXIOM payload and attach the data handler with binary content to the payload.
<soapenv:Body>
<ns1:mtomSample xmlns:ns1="http://ws.apache.org/axis2/c/samples/mtom">
<ns1:fileName>test.jpg</ns1:fileName>
<ns1:image>
<xop:Include xmlns:xop="http://www.w3.org/2004/08/xop/include"
href="cid:1.f399248e-8b39-1db1-3124-0015c53de2e5@apache.org"></xop:Include>
</ns1:image>
</ns1:mtomSample>
</soapenv:Body>
In the above sample payload shown, we place our image file as text within an image element
image_om_ele = axiom_element_create(env, mtom_om_node, "image", ns1, &image_om_node);
data_handler = axiom_data_handler_create(env, image_name, "image/jpeg");
data_text = axiom_text_create_with_data_handler(env, image_om_node, data_handler, &data_om_node);
When sending attachments, you can configure the client either to send the attachment in the optimized format or non-optimized format.
To do this, set the option axis2_options_set_enable_mtom(options,
env, AXIS2_TRUE);
or the setting
<enableMtom>true</enableMtom>
in
axis2.xml
If enableMTOM is set to True, the attachment is sent as it is, out of the SOAP body, using MIME headers. Also the payload will have an XOP:Include element, referring to the MIME part that contains the binary attachment. Sending the attachment as it is, in pure binary format, is called binary optimized format. In the case of binary non-optimized format, where enableMTOM is False, the attachment content is sent in the payload itself, as a base64 encoded string.
user_param is of any type which the user should know how to handle from the callback. The path to the implemented callback should be specified in the axis2.xml as follows.
<parameter name="MTOMSendingCallback" locked="false">/path/to/the/attachment_sending_callback</parameter>
For large attachments users can specify them to be cached either to a file or to a any storage. In order to enable caching user should set either "attachmentDir" or "MTOMCachingCallback" parameters in the axis2.xml. If both are set the callback will be used. If nothing is set attachment will reside in memory.
Following is an example of specifying the attachmentDir.
<parameter name="attachmentDIR" locked="false">/path/to/the/dir/</parameter>
So the attachments will be saved in the specified directory using the attachment content id as the file name.
In the callback case the callback should be implemented using axiom_mtom_caching_callback.h. The following paramter will enbale the caching callback.
<parameter name="MTOMCachingCallback" locked="false">/path/to/the/attachment_caching_callback</parameter>
A sample callback implementation can be found here.Axis2/C allows to set the caching threshold. The default is 1MB. For example to cache attachments which are greater than 10MB in size user need to add the following directive in axis2.xml.
<parameter name="MTOMBufferSize" locked="false">10</parameter>
This will give the control to the users to use the availbale memory even with larger attachments.
When the attachment is cached the ultimate receiver can always identify it by calling ,
if (axiom_data_handler_get_cached(data_handler, env))
{
/* logic for attachment handling */
}
The logic on how to handle the attachment will depend on the mechanism which is used to cached the attachment.
Please have a look at the MTOM related samples in the Axis2/C samples directory.
A module is a set of handlers that helps to extend the message processing behavior of the Axis2/C engine. Modules have the concepts of being Available and Engaged associated with them. Available means modules are deployed in the system but not activated. They will be activated only after being engaged. Every module comes with its own module.xml file . This module.xml file specifies the module specific handlers and the phases into which the handlers are to be placed in the handler chain. Some of the module specific handlers may be put into system predefined phases. In that case, the module.xml file should specify where to put the handlers relative to the others in that phase. Sometimes a module may define its own phase. In that case, some of the module specific handlers may be put into that phase. The handlers added to the system predefined phases (global handlers) are invoked for every message that comes to or goes out from the system. The handlers in the module specific phase are invoked only for the messages invoking the operations that engage that module. Engaging a module means correctly adding the handlers of a particular module to one or more phases. Once the module is engaged, the handlers and the operations defined in the module are added to the entity that engaged them.
Before engaging a module, the following steps have to be followed.
The following is an example of engaging a sample module called the logging module with Axis2/C:
In the module.xml file, the handlers of the module and the phases to which they are to be added have to be specified. Below is the module.xml file of the sample logging module.
<module name="logging" class="axis2_mod_log">
<inflow>
<handler name="LoggingInHandler" class="axis2_mod_log">
<order phase="PreDispatch"/>
</handler>
</inflow>
<outflow>
<handler name="LoggingOutHandler" class="axis2_mod_log">
<order phase="MessageOut"/>
</handler>
</outflow>
<Outfaultflow>
<handler name="LoggingOutHandler" class="axis2_mod_log">
<order phase="MessageOut"/>
</handler>
</Outfaultflow>
</module>
In the above shown module configuration file, the name of the module is logging. There are two handlers in this module, the LoggingInHandler and the LoggingOutHandler. The LoggingInHandler is placed into the PreDispatch phase of the in flow. The LoggingOutHandler is placed into the MessageOut phase of both the out flow and the fault out flow.
The above module.xml file should be copied to a folder named "logging" (because the module name is "logging") inside the AXIS2C_INSTALL_DIR/modules folder. The module libraries containing the handler implementation should also be copied to the same folder. According to the module.xml file shown above, the name of the shared library file should be libaxis2_mod_log.so on Linux and axis2_mod_log.dll on MS Windows.
Module specific phases have to be added after the system
predefined
phases. The following example shows where to add the module specific
phases.
Look for the phaseOrder
elements in the
axis2.xml file. Note the
comment lines:
<!-- User defined phases could be added here -->
You can add user defined phases after the above comment line
into any of the
flows. The type
attribute of the phaseOrder
element
indicates the flow.
For the logging module example, user defined phases are not required. All the module specific handlers are added to system predefined phases as specified in the module.xml file.
The following is an example of engaging the logging module to
the echo
service. This can be done by simply adding <module
ref
="logging"/>
in the services.xml file of the echo
service. This
informs the Axis2/C engine that the module "logging" should be engaged
for
this service. The handlers inside the module will be executed in their
respective phases as described by the module.xml.
<service name="echo">
<module ref ="logging"/>
<parameter name="ServiceClass" locked="xsd:false">echo</parameter>
<description>
This is a testing service, to test if the system is working or not.
</description>
<operation name="echoString">
<!--messageReceiver class="axis2_receivers" /-->
<parameter name="wsamapping" >
http://ws.apache.org/axis2/c/samples/echoString
</parameter>
</operation>
</service>
One important thing to note here is that because the logging module's handlers are placed into the global phases, even though the logging module is engaged only to the echo service, the module will be engaged globally. This is a feature of the Axis2 architecture, not a bug. When invoked, the handlers in a module can check whether the module has been engaged to a particular service, and act accordingly.
If we want to engage a module for every service deployed in
the Axis2/C
system, we can add the <module ref
="logging"/>
entry in
the axis2.xml file. This will inform the Axis2/C engine to invoke the
handlers associated with the module for every message coming in or
going out
for all the services deployed.
On the client side, if <module ref
="logging"/>
is
added in the axis2.xml, the handlers specific to the logging module
will be
invoked for every request the client sends and every response the
client
receives. If only a particular client wants to engage the module, it
can be
done by engaging the module programmatically. This can be done by
adding the
following line in the client code after setting the options.
axis2_svc_client_engage_module(svc_client, env, "module-name");
Remember to replace "module-name" with the name of the module you want to engage. For example to engage the logging module you can use:
axis2_svc_client_engage_module(svc_client, env, "logging");
WS-Addressing provides mechanisms to address Web services and messages. With Axis2/C, you can use both WS-Addressing version 1.0 as well as the submission version.
WS-Addressing is implemented as a module in Axis2/C. Hence as explained in the previous section, the addressing module can be engaged both on the client side as well as on the server side.
The WS-Addressing module can be globally engaged by adding the
<module ref="addressing"/>
line
to the axis2.xml file.
The WS-Addressing module can also be programmatically engaged
using the
following line of code with the service client API
axis2_svc_client_engage_module(svc_client, env, AXIS2_MODULE_ADDRESSING);
WS-Addressing related options can be set using the
axis2_options
struct instance on the client
side. If the
addressing module is engaged, there are no options to be set on the
server
side. The server will employ WS-Addressing if the incoming requests
have
WS-Addressing headers.
There is a mandatory requirement for using WS-Addressing on the client side with Axis2/C. That is to set a WS-Addressing action that represents the operation to be invoked. Example:
axis2_options_set_action(options,env,"http://ws.apache.org/axis2/c/samples/echoString")
In addition to the action, which is mandatory, there are other WS-Addressing related headers that can be sent in a message. Axis2/C supports to set those headers as options at the client level. The following functions are used to set them.
axis2_options_set_reply_to(options, env, reply_to)
Sets the wsa:ReplyTo
header. The
ReplyTo header contains the
endpoint to send reply messages. The ReplyTo header is required when
the
response comes in a separate channel (when using a dual channel).
axis2_options_set_fault_to(options, env, fault_to)
Sets the wsa:FaultTo
header. This
contains the endpoint to
direct fault messages.
axis2_options_set_from(options, env, from)
Sometimes the receiving endpoint requires to know the original
sender of
the message. The wsa:From
header is used in
such cases. The
above function sets the From header.
axis2_options_set_relates_to(options, env, relates_to)
Sets the wsa:RelatesTo
header. This
header contains a unique
ID which is the message ID of a previously exchanged message. It helps
to
identify a previous message that relates to the current message.
A module is an extension point in the Axis2/C engine. Modules
are
primarily used to WS-* specifications. In other words, quality of
service
aspects such as security and reliable messaging can be implemented as
modules
and deployed with the Axis2/C engine.
A SOAP message can contain any number of header blocks. These header
blocks
provide various processing information. In Axis2/C, these various
header
blocks are processed by modules. Some times modules may add header
blocks to
a SOAP message.
Normally a module is a collection of handlers. So writing a
module mainly
consists of writing handlers. There are two interfaces that are
important
when writing a module. They are axis2_module
and
axis2_handler
.
Every module should have three basic functions that are
defined as
function pointer members of the axis2_module_ops
struct. This
struct is defined in the axis2_module.h
header file.
Function Signature | Description |
---|---|
axis2_status_t (AXIS2_CALL * | This function takes care of the module initialization. |
axis2_status_t (AXIS2_CALL * | Shuts down and cleans up the module. |
axis2_status_t (AXIS2_CALL * | This function fills the hash map of the handler create functions for the module. |
The module developer has to implement functions with the above
signatures
and assign them to the members of an axis2_module_ops
struct
instance. Then that struct instance has to be assigned to the ops
member of
an axis2_module
struct instance.
mod_log.c
has the source for the
logging module. Please have a look at the axis2_mod_log_create
function in it to see how an axis2_module
instance is allocated
and how the ops are initialized.
The axis2_mod_log_fill_handler_create_func_map
function adds
the handler create functions to the module's hash map, which stores the
handler create functions. In the mod_log.c
example, the logging module adds
two handlers. The in handler and the out handler that deals with
logging
along with the in-flow and out-flow respectively.
A handler is the smallest unit of execution in the Axis2/C
engine's
execution flow. The engine can have two flows, the in-flow and the
out-flow.
A flow is a collection of phases, and a phase in turn is a collection
of
handlers. A handler is invoked when the phase within which it lives is
invoked. Axis2/C defines an interface called axis2_handler
,
which is to be implemented by all the handlers.
log_in_handler.c
contains the
source code of the in-handler of the logging module. Please have a look
at
the axutil_log_in_handler_create
function to
see how an
axis2_handler
instance is created and how the
invoke function
implementation, axis2_log_in_handler_invoke
is assigned to the
axis2_handler
invoke function pointer. The
invoke is called to
do the actual work assigned to the handler. The phase that owns the
handler
is responsible for calling the invoke function of the handler.
log_out_handler.c contains the source code of the out handler of the logging module. The implementation is similar to the in handler, except that it is placed along the out-flow when deployed.
After writing the module, the module.xml file should be written. The module.xml file contains all the configuration details for a particular module. Please see the sample module.xml file for the logging module.
Please see the Engaging a Module section for more details on how to package and deploy the module.

To build Axis2/C with the Apache HTTP server module, also called mod_axis2, you need to provide the following configuration options on the Linux platform:
./configure --with-apache2=[path to Apache2 include directory] [other configure options]
NOTE: Some Apache2 distributions, specially development versions, install APR (Apache Portable Run-time) include files in a separate location. In that case, to build mod_axis2, use:
./configure --with-apache2=[path to Apache2 include directory] --with-apr=[path to APR include directory]
[other configure options]
Then build the source tree as usual using:
make
make install
This will install mod_axis2.so into your AXIS2C_INSTALL_DIR/lib folder.
On the MS Windows platform, you have to provide the Apache2 install location in the configure.in file with the setting APACHE_BIN_DIR. Example:
APACHE_BIN_DIR = "C:\Program Files\Apache Software Foundation\Apache2.2"
Based on the Apache HTTP server version you are using, you also need to set the setting APACHE_VERSION_2_0_X in the configure.in file. If you are using Apache 2.2 family, this setting should be set to 0,else set it to 1.
APACHE_VERSION_2_0_X = 0
To build the source, you have to run the command
nmake axis2_apache_module
This will build mod_axis2.dll and copy it to AXIS2C_INSTALL_DIR\lib directory.
NOTE: To execute some of the commands given below, you might require super user privileges on your machine. If you are using the binary release of Axis2/C, please note that it is built with Apache 2.2.
Copy the mod_axis2 shared library (libmod_axis2.so.0.6.0 on Linux and mod_axis2.dll on MS Windows) to the Apache2 modules directory as mod_axis2.so
On Linux
cp $AXIS2C_HOME/lib/libmod_axis2.so.0.6.0 /usr/lib/apache2/modules/mod_axis2.so
On MS Windows
copy /Y "%AXIS2C_HOME%\lib\mod_axis2.dll" C:\Apache2\modules\mod_axis2.so
Edit the Apache2's configuration file (generally httpd.conf) and add the following directives at the end of the file.
LoadModule axis2_module MOD_AXIS2_SO_PATH
Axis2RepoPath AXIS2C_INSTALL_DIR
Axis2LogFile PATH_TO_LOG_FILE
Axis2LogLevel LOG_LEVEL
Axis2ServiceURLPrefix PREFIX
Axis2MaxLogFileSize SIZE_IN_MB
<Location /axis2>
SetHandler axis2_module
</Location>
Please note that you have to fine tune the above settings to
mach your
system.
MOD_AXIS2_SO_PATH has to be replaced with the full path to
mod_axis2.so,
for example, /usr/lib/apache2/modules/mod_axis2.so
on Linux, or C:\Apache2\modules\mod_axis2.so
on MS Windows
AXIS2C_INSTALL_DIR has to be replaced with the full path to Axis2/C
repository, for example, /usr/local/axis2
on
Linux, or c:\axis2c
on MS Windows. Note that
repository path should
have read access to the daemon user account under which the Apache2
HTTPD
process is run.
PATH_TO_LOG_FILE has to be replaced with the full path to where you
wish to
have the Axis2/C log file, for example, /tmp/axis2.log
on Linux, or C:\Apache2\logs\axis2.log
on MS
Windows. Note that the log
file path should have write access to the daemon user account under
which the
Apache2 HTTPD process is run.
LOG_LEVEL has to be replaced with one of the following values: crit,
error,
warn, info, debug, trace. These log levels have the following meanings:
SIZE_IN_MB must be replaced by the size of the particular
resource in MB, rounded to
the nearest whole value.
PREFIX has to be replaced with the prefix to be used with the service
endpoints. This is optional and defaults to "services".
As an example, if you have "web_services" as the prefix, then all the
services hosted would have the endpoint prefix of :
http://localhost/axis2/web_services
If you wish, you can also change the location as well by replacing
"/axis2" in <Location /axis2> setting with whatever you
wish.
NOTE: If you want to use a Shared Global Pool with Apache you have to give another entry called Axis2GlobalPoolSize.You have to give the size of the shared global pool in MB.If you doesn't set the value or if you set a negative value Apache module doesn't create shared global pool.
Axis2GlobalPoolSize SIZE_IN_MB
To ensure that everything works fine, start Apache2 (restart
if it is
already running) and test whether the mod_axis2 module is loaded
correctly by
accessing the URL: http://localhost/axis2/services.
This should show the list of services deployed with Axis2/C. Then you should be able to run clients against this endpoint. Example:
echo http://localhost/axis2/services/echo
In case things are not working as expected, here are some tips on how to troubleshoot:
Use the Axis2/C VC project or makefile to buid the component. If you are using the makefile to build the source, you have to run the command
nmake axis2_iis_module
In this document I assume that the mod_axis2_IIS.dll
is in the directory c:\axis2c\lib
and
AXIS2C_HOME
is c:\axis2c
Add the following key to the registery.
HKEY_LOCAL_MACHINE\SOFTWARE\Apache Axis2c\IIS
ISAPI
Redirector
Add a string value with the name AXIS2C_HOME
and a
value of c:\axis2c
Add a string value with the name log_file
and a value
of c:\axis2c\logs\axis2.log
Add a string value with the name log_level
.
The value
can be either trace
, error
,
info
, critical
, user
,
debug
, or warning
.
You can add a string value with the name services_url_prefix
. This is optional and defaults to "/services".
As an example, if you have "/web_services" as the prefix, then all the
services hosted would have the endpoint prefix of :
http://localhost/axis2/web_services.
Note: don't forget the / at the begining.
If you wish, you can also change the location as well by adding a string value with the name axis2_location
. This is also optional and defaults to /axis2.
If you have /myserser as the value you can access your web services with a url like http://localhost/myserver/services.
Note: Don't forget the / at the beginning.
Now you can do all the registry editing using the JScript file
axis2_iis_regedit.js provided with the distribution. When you build
axis2/C with the IIS module the file is copied to the root directory of
the binary distribution. Just double click it and everything will be
set to the defaults. The axis2c_home is taken as the current directory,
so make sure you run the file in the Axis2/C repository location (or
root of the binary distribution). If you want to change the values you
can manually edit the the .js file or give it as command line arguments
to the script when running the script. To run the jscript from the
command line use the command :\cscript axis2_iis_regedit.js optional arguments
. We recomend the manual editing as it is the easiest way to specify the values.
IIS 5.1 or Below
Using the IIS management console, add a new virtual directory to your IIS/PWS web site. The name of the virtual directory must beaxis2
. Its
physical path should be the directory in which you placed
mod_axis2_IIS.dll (in our example it is
c:\axis2c\lib). When creating this new virtual directory, assign
execute access to it.
By using the IIS management console, add mod_axis2_IIS.dll as a filter in your IIS/PWS web site and restart the IIS admin service.
IIS 6 & 7
Using the IIS management console, add the mod_axis2_IIS.dll as a Wildcard Script Map.Please don't add the mod_axis2_IIS.dll as a filter to IIS as in the IIS 5.1 case.
Note: If the Axis2/C failed to load, verify that Axis2/C and its dependent DLLs are in the System Path (not the user path).
In order to allow an Axis2/C client to communicate with an SSL enabled server, we need to compile Axis2/C with SSL support enabled.
To build with SSL client support, first of all, make sure you
have
installed OpenSSL
on your machine. Then
you can start building with SSL client support. This can be achieved on
Linux
by configuring Axis2/C with the --enable-openssl=yes
option.
Example
%./configure --enable-openssl=yes --prefix=${AXIS2C_HOME}/deploy
%make
%make install
On MS Windows, set ENABLE_SSL=1
in
the
configure.in
file and run the nmake
all
command.
If you need SSL client authentication, Axis2/C requires you to
provide the
client certificate and the private key file in a single file. Such a
file
which contains both the certificate and relevant private key is called
a
certificate chain file. Creating such a file is very easy. Assume that
the
client certificate is stored in a file named client.crt
and the
private key is stored in a file named client.key
.
Then the
certificate chain file can be created by concatenating the certificate
file
and the private key file in that order, in to another file, say
client.pem
.
On Linux you can do this as follows: %cat
client.crt client.key >
client.pem
On MS Windows, you can do this by copying the contents of client.crt and client.key files and saving them in a file named client.pem using Notepad.
Uncomment the following in axis2.xml
to enable https transport receiver and https transport sender.
Axis2/C will then be able to recognize the "https" sheme in a given end
point reference (EPR) and use SSL transport.
<transportReceiver name="https" class="axis2_http_receiver">
<parameter name="port" locked="false">6060</parameter>
<parameter name="exposeHeaders" locked="true">false</parameter>
</transportReceiver>
<transportSender name="https" class="axis2_http_sender">
<parameter name="PROTOCOL" locked="false">HTTP/1.1</parameter>
</transportSender>
For the SSL client to work, the file containing the CA
certificate should
be given as SERVER_CERT
parameter in the
axis2.xml file. If you
need client authentication, you can also set the parameters in the
axis2.xml
file to specify the client certificate, private key, and the passphrase
for
the client private key. Parameter names for these are:
KEY_FILE
- certificate chain file
containing the client's
certificate and the private key (Please refer to the creating the client certificate chain
file
section)
SSL_PASSPHRASE
- passphrase used to encrypt
the private key
file.
Example:
<parameter
name="SERVER_CERT">/path/to/ca/certificate</parameter>
<parameter
name="KEY_FILE">/path/to/client/certificate/chain/file</parameter>
<
parameter
name="SSL_
PASSPHRASE">passphrase</parameter>
For testing purposes, you can use the server's certificate
instead of the
CA certificate. You can obtain this by running the command openssl
s_client -connect <servername>:<port>
and copying the
portion of the output bounded by and including:
-----BEGIN CERTIFICATE-----
-----END CERTIFICATE-----
On Linux, if you run the following piece of code, the server
certificate
will be saved to a file cert.pem
:
echo |\
openssl s_client -connect <servername>:<port> 2>&1 |\
sed -ne '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p' > cert.pem
NOTE: Instead of setting
these parameters in the axis2.xml
file, you can also set these parameters programmatically in your client
code.
Here we will only look at the configuration of the Apache HTTP Web server. Refer to the 'Deploying with Apache HTTP Server Version2.x' section for information on deploying Axis2/C as an Apache module.
For more detailed information on SSL configuration, please refer to Apache2 SSL/TLS documentation.
In the httpd.conf
file, add the
following configuration
statements (in addition to other necessary configuration):
SSLEngine on
SSLCertificateFile /path/to/server/certificate/file
SSLCertificateKeyFile /path/to/private/key/file
SSLCACertificateFile /path/to/CA/certificate/file
SSLVerifyClient require
SSLVerifyDepth 1
NOTE: The last two lines, SSLVerifyClient
and
SSLVerifyDepth
are only needed when you need
client
authentication.
When using a proxy, there are two methods for specifying proxy settings:
When using proxy authentication, there are three methods for specifying proxy authentication settings:
<transportSender name="http" class="axis2_http_sender">
<parameter name="PROTOCOL" locked="false">HTTP/1.1</parameter>
<parameter name="PROXY" proxy_host="127.0.0.1" proxy_port="8080" proxy_username="" proxy_password="" locked="true"/>
</transportSender>
You can specify proxy authentication settings using the following function with the service client:
axis2_svc_client_set_proxy_with_auth(axis2_svc_client_t *svc_client,
const axutil_env_t *env,
axis2_char_t *proxy_host,
axis2_char_t *proxy_port,
axis2_char_t *username,
axis2_char_t *password);
You can specify proxy authentication settings using the following function with the service client options:
axis2_options_set_proxy_auth_info(
axis2_options_t * options,
const axutil_env_t * env,
const axis2_char_t * username,
const axis2_char_t * password,
const axis2_char_t * auth_type);
In auth_type
, use Basic
to force Basic Authentication or Digest to force
Digest
Authentication. Leave this field NULL if you are not forcing
authentication.
You can also predetermine whether proxy authentication is required. This can be done by calling the function below:
axis2_options_set_test_proxy_auth(
axis2_options_t * options,
const axutil_env_t * env,
const axis2_bool_t test_proxy_auth);
Set test_proxy_auth
to AXIS2_TRUE
to enable testing.When testing is enabled, the request will be sent
without without adding authentication information. If it fails, and
requests Authentication Information, the request type of authentication
will be saved. This information can be obtained in the following manner:
axis2_svc_client_get_auth_type(
const axis2_svc_client_t * svc_client,
const axutil_env_t * env);
This will return either Basic, Digest or NULL according to the type of authentiation requested. In addition to that, after each request made through the service client, you can check whether authentication was required.
axis2_svc_client_get_proxy_auth_required(
const axis2_svc_client_t * svc_client,
const axutil_env_t * env);
Please take a look at the echo_blocking_auth
sample for more information on how to use these methods to identify
proxy Authentication requirements.
When using HTTP authentication, there are two methods for specifying proxy authentication settings:
<transportSender name="http" class="axis2_http_sender">
<parameter name="PROTOCOL" locked="false">HTTP/1.1</parameter>
<parameter name="HTTP-Authentication" username="your username" password="your password" locked="true"/>
</transportSender>
You can specify HTTP authentication settings using the following function with the service client options:
axis2_options_set_http_auth_info(
axis2_options_t * options,
const axutil_env_t * env,
const axis2_char_t * username,
const axis2_char_t * password,
const axis2_char_t * auth_type);
In auth_type
, use Basic
to force HTTP Basic Authentication or Digest to
force HTTP Digest
Authentication. Leave this field NULL if you are not forcing
authentication.
You can also predetermine whether HTTP authentication is required. This can be done by calling the function below:
axis2_options_set_test_http_auth(
axis2_options_t * options,
const axutil_env_t * env,
const axis2_bool_t test_http_auth);
Set test_http_auth
to AXIS2_TRUE
to enable testing.When testing is enabled, the request will be sent
without without adding authentication information. If it fails, and
requests Authentication Information, the request type of authentication
will be saved. This information can be obtained in the following manner:
axis2_svc_client_get_auth_type(
const axis2_svc_client_t * svc_client,
const axutil_env_t * env);
This will return either Basic, Digest or NULL according to the type of authentiation requested. In addition to that, after each request made through the service client, you can check whether authentication was required.
axis2_svc_client_get_http_auth_required(
const axis2_svc_client_t * svc_client,
const axutil_env_t * env);
Please take a look at the echo_blocking_auth
sample for more information on how to use these methods to identify
HTTP Authentication requirements.
WSDL2C tool that comes with Axis2/Java supports the generation of Axis2/C stubs and skeletons for WSDL files. This is a Java tool that can be used to generate C code that works with Axis2/C API. You should use Axis2/Java SVN revision 529533 or later revisions. You can download the Axis2/Java nightly build and use those binaries to generate code. Check out a basic guide on the Java tool.
Before you run the tool, make sure that all the .jar library files that come with Axis2/Java are added to the CLASSPATH environment variable.
The tool can be run with the following parameters and generate the service skeleton and other required files with ADB (Axis Data Binding) support.
java org.apache.axis2.wsdl.WSDL2C -uri interoptestdoclitparameters.wsdl -ss -sd -d adb -u
To understand the meanings of the options used with the tool, please have a look at the Java tool documentation.
If you need an XML in/out programming model, you can just
ignore the data
binding support. To generate code with no data binding support, just
replace
-d adb -u
, that was used in a previous
command, with -d
none
.
java org.apache.axis2.wsdl.WSDL2C -uri interoptestdoclitparameters.wsdl -ss -sd -d none
The WSDL file, interoptestdoclitparameters.wsdl
,
used in the
above command examples can be found in
<axis2_src_dir>/test/resources
directory.
Once the code is generated, you have to implement the business logic for the service. For this, locate the skeleton source file from the generated files. To identify the locations where you can place your business logic in line with the operations defined in the WSDL file that you used to generate code, look for the comment lines:
/* Todo fill this with the necessary business logic */
You can also go through the generated header files and understand the API in line with the WSDL file that you used to generate the code.
The WSDL2C code generator tool provides support for generating client stubs as well. You can generate the required stubs from a given WSDL with the other supporting files. Use following parameters to generate the Axis2/C client stub code with ADB support.
java WSDL2C -uri interoptestdoclitparameters.wsdl -d adb -u
In order to ignore the data binding support and use a raw XML in/out model, just use the following parameters.
java WSDL2C -uri interoptestdoclitparameters.wsdl -d none
Like in the case of service skeletons, you have to fill in the business logic as required in the client stubs as well. To do this, go through the header files generated and understand the API in line with the WSDL file that you used to generate the code.

Axis2/C supports two main deployment models,
Also, it is requirement that you have zlib. Most Linux systems do have zlib by default, but would require zlib development packages. More information can be found here. For MS Windows systems, you can download it from here.
Next, you will have to build Axis2/C enabling Archive Based
Deployment. On Linux, you need to set the --with-archive=[path_to_zlib_headers]
Example:
%./configure --with-archive=/usr/include/ --prefix=${AXIS2C_HOME}/deploy
%make
%make install
On MS Windows, set WITH_ARCHIVE = 1
in the
configure.in
file and run the nmake
all
command. Please note that you have to specify the
directory where you can find the zlib binary, for a MS Windows system.
This can be done by setting the ZLIB_BIN_DIR
in the
configure.in
file.
Once you have successfully completed the installation, you will have to deploy services as archives in order to make use of this deployment model. Please note that directory based deployment can coexist with the archive based deployment model. Therefore, you can alternatively use either of the two.
You will merely have to add your existing service libraries
and the services.xml file into an archive. For example, in order to
deploy the sample echo service as an archive, you can zip the echo
folder found in the AXIS2C_BIN_DIR/services
directory. You can optionally rename your zip file, to have the .aar
extension.
Please note that all such services deployed as archives should
also be placed inside the AXIS2C_BIN_DIR/services
directory. Now, when ever you start your Simple Axis2 Server, or any
Axis2/C module attached to any other server, your services deployed as
archives, will also get loaded.
Similar to services, you also can deploy modules as archives.
You also can optionally rename your zip files to have the extension, .mar
as in service archives.
Your module archives must be placed in the AXIS2C_BIN_DIR/modules
directory.
Please note that there are a few known issues when running
archive based deployment, mainly on Linux based systems.
TCPMon is a TCP Monitor tool provided by Axis2/C for monitoring payloads exchanged between client and server. If you are using a source distribution, this may or may not be built for you by default. Thus, to get started, you may require building it from source.
On Linux
./configure --prefix=${AXIS2C_HOME} --enable-tests=no
make
On MS Windows
nmake tcpmon
Please note that in most Linux based installations, this will
most probably be built for you. Once you've done with the building
process, you can find the executable at ${AXIS2C_HOME}/bin/tools
on Linux, or at %AXIS2C_HOME%\bin\tools
on MS
Windows.
By default, the TCPMon tool will listen on port 9090
and reply to port 8080
.
The default target host will be localhost
and tcpmon_traffic.log
will be the default log_file. If you want to change any of these
settings run ./tcpmon -h
on Linux, or tcpmon.exe
-h
on MS Windows for more information.
The TCPMon tool does depend on the Axis2/C Util, Axis2/C AXIOM and Axis2/C Parser libraries. Thus, if you want to use TCPMon to monitor payloads in any other message transfer, independant of the Axis2/C engine, you will have to build those dependant libraries too. In addition to that, TCPMon does not depend on the Axis2/C Core and installing the Axis2/C engine is not always a pre-requisite to run TCPMon.
The axis2.xml file is the configuration file for Axis2/C. It has 6 top level elements. They are parameter, transportReceiver, transportSender, module, phaseOrder and messageReceiver.
