Class RMIRemoteSessionControllerDispatcher

java.lang.Object

javax.rmi.PortableRemoteObject

org.eclipse.persistence.sessions.remote.rmi.iiop.RMIRemoteSessionControllerDispatcher

All Implemented Interfaces:

java.rmi.Remote, RMIRemoteSessionController

public class RMIRemoteSessionControllerDispatcher
extends javax.rmi.PortableRemoteObject
implements RMIRemoteSessionController

RemoteSessionController sits between the remote session and the session. Any interaction between these two classes takes place through this object. As the object extends unicast remote object it listens to only single remote session during runtime.
