How can I receive messages asynchronously?

Question

Hi,
I am reading the AQ User's Guide, and it talks about that Topic Publisher-Subscriber model and MessageListener.
I wrote a Publisher code which creates a ADT payload and publishes. I also wrote a Subscriber which has the following
code segment:
subs[0] = ((AQjmsSession)tsess).createDurableSubscriber(topic, "PROG1", null, false, Emp.getFactory());
subs[1] = ((AQjmsSession)tsess).createDurableSubscriber(topic,"PROG2", null, false, Emp.getFactory());
MessageListener topicListener = new MesgListener(tsess);
tsess.setMessageListener(topicListener);
System.out.println("To end program, enter Q or q, then <return>");
I start the Subscriber first and waits for incoming messages from Publisher. Then in another window, I execute the
Publisher. I ASSUME that when I execute the Publisher, Subscriber should get the Topic and call
tsess.setMessageListener(topicListener). But this is not working, I am not seeing anyting in the Subscribe window.
Could you please let me know what I am doing wrong?
Thanks,
Mustafa

I am seeing the same thing, and would really like to stick with using the AQjms interface if possible. Does anyone know of a work-around? Do I need to use the pl/sql dequeue method? Thanks in advance, Chris
