EJBLocalObjectInvocationHandlerDelegate

public class EJBLocalObjectInvocationHandlerDelegate extends Object implements InvocationHandler
This class is used as a "proxy" or adapter between the business interface proxy and the EJBLocalObjectInvocationHandler. An instance of this class is created for each business interface of a bean. All java.lang.Object methods and mthods of IndirectlySerializable are handled by this InvocationHandler itself while the business interface methods are delegated to the delegate (which is the EJBLocalObjectInvocaionHandler).
