A Handler represents a piece of message processing functionality in Axis2.
An instance of MessageReceiver can be setup to receive messages.
When you want to initialize database connections , starting threads and etc..
This the base class for all dispatchers.
There is one engine for the Server and the Client. the send() and receive() Methods are the basic operations the Sync, Async messageing are build on top.
This class provide a very convenient way of creating server and deploying services.
If the service implementation has an init method with 1 or 2 message context as its parameters, then the DependencyManager calls the init method with appropriate parameters.
A Deployable is a container for something (Phases, Handlers) which wants to be deployed in an ordered and constrained fashion via a DeployableChain.
A DeployableChain is a container which manages dependencies between Deployables.
This type encapsulates an enumeration of possible message processing instruction values that may be returned by a handler/phase within the runtime.
A Phase is an ordered collection of Handlers.
