I wouldn't expect the consumer on L2 to receive any of them anonymous wrote : | Eventually, they are sucked over to L2-Q2 and L2 finally receives them. | I guess this happens when you close the consumer on L1? If you want your response queue to be only usable by your connection, you can use the distributed request/response pattern. I.e. create a clustered temporary queue and pass that as the "replyTo" header in the message. When the message is consumed, a reply is sent back to the destination that's specified in that header. Sounds like that's what you want to do. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4110981#...
