Subject dynamic topic and listener
Date Sun, 11 Apr 2010 06:04:20 GMT
googled but still can not get detailed enough info.

my use case is that a chat room needs to be dynamically created, so a dynamic listener.

how do I do this in Java ? mentioned that we can use
session.createTopic() to create a dynamic topic. So I assume that we can first have a static
queue newChatRoom, with a listener who will create the dynamic topic:
public void onMessage(Message message, Session session) throws JMSException {
Topic topic = session.createTopic ("newTopic");

But how do I register a new listener for this dynamic topic ?
Another question, how do I delete the topic when all people left the room ?
