I cannot receive the messages:
TemporaryTopic topic = session.createTemporaryTopic();
// topic name is something like this:
// ID:lchu-2087-1271131089285-2:0:1
MessageConsumer consumer = session.createConsumer(topic);
consumer.setMessageListener(this);
Looking at server side log message, MessageListenerServlet received the msg but
the listener did not.
Any idea ?

I guess:
- to be able to delete the Topic/Queue, I should create the
temporaryTopic/temporaryQueue
- then create the MessageConsumer:
consumer = session.createConsumer (topic);
- set the lsitener
consumer.setMessageListener (this);
Am I correct ?

Subject: dynamic topic and listener
Hello,
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 ?
http://activemq.apache.org/how-do-i-create-new-destinations.html 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 ?
