Publish and Subscribe

[DavidShaw <da...@gmail.com>]

I've been looking at creating a queue that would support "publish and
subscribe".  To be specific, I want to create a queue/topic, and when I send
a given message to it, multiple consumers that subsequently pull from the
queue will get that message, one copy per consumer.  

Client 1 subscribes to queue X
Client 2 subscribes to queue X

Publisher 1 pushes message A to X
Publisher 2 pushes message B to X

Client 1 pulls, gets message A
Client 1 pulls, gets message B
Client 2 pulls, gets message A
Client 2 pulls, gets message B

I looked at this page:
http://activemq.apache.org/virtual-destinations.html

but I don't really see if I can solve this problem using it.  I can think of
a workaround, but is it possible to do exactly the user story I described
above?

Thanks, I'm still trying to figure this out, but I think it will work for me
if I can.

What you describe sounds just like normal publish/subscribe - am I  
missing something?
