multiple clients one server architicture using queues

kalowand
My case is as follow, I have one master machine and 7 clients machine. I add activemq between these machines. The clients machine send messages to the master machines and the master machine send individual messages to each client.  
I implement the following solution, I am using a queues structure as a medium for communication. The solution works for only one client server, but when I add another client to this architecture the activemq does not receive any messages. until I turn off the first client. giving the following exception.


javax.jms.InvalidClientIDException: Broker: localhost - Client: NC_localhost_outbound already connected from tcp://0.0.0.77:59730

You're using topics?  Do you have to?

Re: multiple clients one server architicture using queues

Tim Bain
In reply to this post by kalowand
It sounds like maybe you're trying to connect from multiple consumers with
non-unique client IDs.  Each consumer needs a unique ID; can you confirm
that you're using unique IDs in each client?  Though I'm surprised you
wouldn't see that message till *after* the first client disconnects...

Re: multiple clients one server architicture using queues

Tim Bain
Also, is each client supposed to get each message?  Or are you using
selectors to ensure that each client only gets messages destined for it?

Your problems sound related to your clients (for which you've posted no
code/configs), not your broker, so more detail about them might help bring
the problem to light...
