oracle.toplink.remote.rmi.wls
Class WLSClusteringService

java.lang.Object
oracle.toplink.remote.AbstractClusteringService
oracle.toplink.remote.AbstractJNDIClusteringService
oracle.toplink.remote.rmi.wls.WLSClusteringService

All Implemented Interfaces:

java.lang.Runnable

public class WLSClusteringService

extends AbstractJNDIClusteringService

PURPOSE:To Provide a framework for offering customers the ability to automatically connect multiple sessions for synchrnization.

Descripton:This thread object will place a remote dispatcher in the specified JNDI space. it will also monitor the specified multicast socket to allow other sessions to connect. This Particular class has been configured to use the RMI transport protocols. This class is only valid for use in a clustered WebLogic application server.

See Also:

CacheSynchronizationManager, oracle.toplink.remote.

Constructor Summary

WLSClusteringService(Session session)
PUBLIC: Creates a WLSClusteringService

Method Summary

oracle.toplink.internal.remote.RemoteConnection	createRemoteConnection(java.lang.String sessionId, java.lang.Object remoteObject) ADVANCED: This method should return a remote connection of the appropraite type for use in the synchronizatio
oracle.toplink.internal.remote.RemoteConnection	createRemoteConnection(java.lang.String sessionId, java.lang.String jndiHostURL) ADVANCED: This method should return a remote connection of the appropraite type for use in the synchronizatio
void	deregisterDispatcher() ADVANCED: This method will deregister the dispatcher for this session from JNDI on the specified host.
java.net.MulticastSocket	getCommunicationSocket() ADVANCED: Returns the socket that will be used for the multicast communication.
javax.naming.Context	getContext(java.util.Hashtable contextProperties) ADVANCED: Returns the active JNDI Context to store the remote service in no properties are required in WebLogic as all defaults should be globally available in the VM
java.lang.Object	getDispatcher() ADVANCED: This is the object that will be placed in JNDI to provide remote synchronization services
oracle.toplink.internal.remote.RemoteConnection	getLocalRemoteConnection() ADVANCED: This method should return a Remote Connection of the appropriate type that references the Remote dispatcher for this Session
void	registerDispatcher() ADVANCED: This method will register the dispatcher for this session in JNDI on the specified host.
void	run() This is the main execution method of this class.
