So looking at the documentation section 21.11.1

21.11.1. Configuration
Before you can subscribe to a JMS topic, you must first configure a list of the topics that can be subscribed to by Seam Remoting. List the topics under org.jboss.seam.remoting.messaging.subscriptionRegistry.allowedTopics in seam.properties, web.xml or components.xml.

There also should be an entry for this also somewhere for the following

<remoting:remoting poll-timeout="5" poll-interval="1"/>

I don't see either configured for the chatroom example.

Can someone provide a full working example of using remoting with JMS Topic subscriptions?

Thanks, S.D.
