findClass in class URLClassLoader

Parameters:

name - String Name of the file to be loaded

Returns:

Class return a class object if it found else will return null or a ClassNotFoundException

This method has been overridden in the following way 1. It calls the super class and checks to see whether the class is there If the class is found then return it, else if super return ClassNotfoundException 2. Check whether the entry corresponding to the class name exists in one of jar files in /lib director 3. If it is there get the byte array out of that and create a Class object out of that by calling "defineClass()" , if it succeeds then return that else 4. Throw a ClassNotFoundException

ClassNotFoundException
