Toplink Cache Sync problem

Question

Hello All,
I have configured RCM like this in my code, we are using JBoss 4.0.5
public void configureRemoteCommandManager(String hostname,
int portNumber,
String connectionFactoryName,
String schemaName,
Server session) {
     //define the Command Manager
     RemoteCommandManager commandMgr = new RemoteCommandManager((CommandProcessor)session);
     //set local host URL. In JMS, the local host URL is optional and is used by logging
     //to trace the message sender for debugging purposes
     String localHostName = "";
          try {
               localHostName = InetAddress.getLocalHost().getHostName().toLowerCase();
          } catch (UnknownHostException e) {
               e.printStackTrace();
     commandMgr.setUrl("jnp://" + localHostName + ":" + portNumber);
     //define the JMS transport
     JMSTopicTransportManager transportMgr = new JMSTopicTransportManager(commandMgr);
     transportMgr.setTopicHostUrl("jnp://" + hostname + ":" + portNumber);
     //transportMgr.setTopicConnectionFactoryName("jms/TopLinkTopicConnectionFactory");
     transportMgr.setTopicConnectionFactoryName(connectionFactoryName);
     transportMgr.setTopicName( "topic/testTopic");
     transportMgr.setUserName("user");
     transportMgr.setPassword("pass");
          //Initial context factory name is default to
     transportMgr.setInitialContextFactoryName("org.jnp.interfaces.NamingContextFactory");
     //hook up the components
     commandMgr.setTransportManager(transportMgr);
     session.setCommandManager(commandMgr);
     //turn on distributed cache synchronization with RCM
     session.setShouldPropagateChanges(true);
     //Start joining the cluster
     if(session.isConnected ()) {
          session.getCommandManager().initialize();
          logger.info("RemoteCommandManager initialized");
     } else {
          session.login();
          logger.info("RemoteCommandManager login successful");
This code doesn't throw any exception, but when I am running Toplink in Cluster, objects are not getting refreshed.
I am seeing following in my log.

Looks like updates are coming from remote box, then why objects are not getting refreshed even though they are in memory.
Any input is really valuable.
Thanks

From the log it seems that the events are getting processed. What type of cache coordination are you using in your descriptors (cacheSynchronizationType)? If you have configured them to use invalidation, the objects will not be refreshed until the next time they are accessed (read). If you are using change sets then they should get updated in the cache.
You can check the contents of the change set that is broadcast using the Session event preDistributedMergeUnitOfWorkChangeSet.
