[jboss-user] [JBoss Messaging] - JBM Topic Pub-Sub

I would like to get some input from the JBM community relating to publish/subscribe models using JBoss Messaging.

I have a web service that takes a request and and subscribes that entity to a particular topic(s).  I am having trouble maintaining state for the various subscriptions to particular topics.  It seems that the javax.jms.Session that I use to create the subscribers doesn't maintain the information.  Maybe the answer lies in my misunderstanding of how JBM works but I am going to walk you through what I'm doing to accomplish my pub-sub model.

1.  ConnectionFactory looked up through jndi -> /ConnectionFactory
2.  A Connection is created from the factory.
3.  A Session is created from the Connection

>From here, I can create the subscribers and verify that they exists by publishing to them immediately.  I can dynamically create new topics by using the ServerPeer and MBeans.  I can't figure out how to keep all subscribers active.  I have tried a simple unit test, using only 1 ConnectionFactory, Connection and Session and still, no dice.  Is there a configuration file that enables persistence?
