Hi Rami,

This is a belated reply but wondering if you might be able to help in
configuring WAS and AMQ.

We have followed a similar approach to that listed below by yourself, but we
now connect to an external jndi name prefixed with
dynamicQueues/queue/testQueue.

However when our MDB reconnects to the above testQueue and it has data
against the queue we can't reconnect and WAS fails to start properly. Have
you come across any issues like this ?

If we clear down our testQueue so it has 0 messages on it then our mdb
connects fine and processes away.

I'm suspecting that dynamicQueues is attempting to create our testQueue
again, but this already exists, have you any experience of this ?

Thanks,
Steve.
