Hello,
I didn't hear from anyone on this and have posted this as a bug against
1.4.4. -- Bug 188. I'm really interested in hearing others' opinions on
this subject.

Hello,
I just installed 1.4.3. The good news is that my previous problems with
JMS subscribers, when running as auto-started clients, not getting
messages delivered is resolved. However, it appears that the
auto-started client's message handler (onMessage()) is invoked within
the transaction context of the publishing EJB call. Is this expected
behavior? I would think that the message handlers would be invoked
outside of the transaction. If this is expected behavior, how can I
design around it?
Here's a stacktrace that shows the calls (the non-reentrant exception, I
believe, is an artifact of the problem) The flow is that the EntityBean
(datawatchItemBean), in its postCreate publishes a message and an
auto-started client (DataWatchEngine) subscribes to these messages.
I'm not an expert on JMS (barely getting started with messaging) and
would appreciate all help.
Thanks,
Vidur
