Hallo I am experimenting with a MDB which should also be able to send back a message.
On JBoss 4.2.2.GA out of the box.

I had also tried looking up the QueueConnectionFactory and the queue.
For the queue I had received a NameNotFoundException. Although the queue is clearly bound.
| +- queue (class: org.jnp.interfaces.NamingContext)
| | +- D (class: org.jboss.mq.SpyQueue)
| .....
| | +- BafoegQueue (class: org.jboss.mq.SpyQueue)
| | +- BafoegRepsonseQueue (class: org.jboss.mq.SpyQueue)
|
I have both tried "queue/BafoegRepsonseQueue"
and "BafoegRepsonseQueue".
Can anybody help me with this?
Thanks,
Hans
