Hello, I have a similar problem. I cannot attach my topology as it is highly sensitive. I have 2 servers, a jboss-mq server and a jboss-messaging server. I deploy an EAR in the JBOSS-MQ server which should connect to the queues on the Jboss Messaging server. I already have the same configurations you have suggested but I have the same problem.
