org.jboss.ejb
Interface EJBProxyFactory

All Superinterfaces:: AllowedOperationsFlags, ContainerPlugin, GenericEntityObjectFactory, org.jboss.system.Service

All Known Implementing Classes:: JBossMessageEndpointFactory, JMSContainerInvoker, ProxyFactory

public interface EJBProxyFactory
extends GenericEntityObjectFactory, ContainerPlugin

This is an interface for Container plugins. Implementations of this interface are responsible for receiving remote invocations of EJB's and to forward these requests to the Container it is being used with.

It is responsible for providing any EJBObject and EJBHome implementations (which may be statically or dynamically created).

Before forwarding a call to the container it must call Thread.setContextClassLoader() with the classloader of the container. It must also handle any propagated transaction and security contexts properly. It may acquire the TransactionManager from JNDI.

Moved from typed return to Object to allow for optimizations in creation
Per Dain Sundstrom requests removed the Remote Exception.
The Container Invoker is going to be replaced by the ProxyFactory
