Hi,

I have JBoss-4.0.2 and JBoss-5.1.0.GA on my machine and I am trying to run both at the same time. I am running the "all" configuration for both of them. I've changed the ports for jboss 5 to use ports-02 and jboss 4 is using the default ports. Now when i start Jboss4 first it starts fine and then I start jboss5 is throws exception that:

2009-09-28 17:09:01,655 ERROR [org.jboss.messaging.util.ExceptionUtil] (main) Queue[/queue/DLQ] startService

Anyways but the jboss starts up. So when both are up there is a client deployed in jboss4 which connects to a particular queue which is deployed on jboss4 and not on jboss5. When it tries to put the message on queue, It throws error as following:

2009-09-28 15:46:47,891 DEBUG [net.plus.envoy.bt.jms.JmsSenderImpl] Queued message scheduled to be sent at Mon Sep 28 15:47:47 BST 2009

Don't know why is it using org.jboss.jms.client.JBossConnectionFactory instead of using jboss mq as queue is on jboss4.

Any idea?

Thanks
