Destination does not exist while creating it?

[jbaker_softcomms]

I get JMS application error in my client when trying to create a queue to receive user messages. The server gives me another. It seems to make no sense to me as obviously the destination doesn't exist as I am trying to create it. Maybe I have missed something obvious.
Please help me, I am not used to using JBossMQ...

----- Server output ----

At

Queue queue = session.createQueue(MESSAGE_P2P_ROOT + userId

you are not actually "creating" the queue, rather a reference to it. The JMS API does not provide a vendor neutral way of creating queues. They are "administered objects" from memory, and everything regarding creation/management is done in a vendor-specific way. In this case, you create them using the JMS interface (I think), or in jboss.jcml.

Damn!!!... This must be a feature request then... The previous implementation I was using would create one if it didn't exist this way!!.. Oww.. How do you do this with JBossMQ right now? I can abstract out the creation stuff... The idea here is that a user logged in creates a queue and other users know if the user is around and can receive messages by the existance of the queue... Pretty simple stuff really... But I need dynamic queue creation...

It's covered in the manual.
