Hi,
we are using the qpid-jms client with Artemis 2.6. I am having big troubles
getting message rejection/redelivery working as expected. I already opened an
issue against Artemis https://issues.apache.org/jira/browse/ARTEMIS-1618
(https://issues.apache.org/jira/browse/ARTEMIS-1618)but the more I play around
with my test case the more I wonder if it may be an issue in qpid-jms itself.
What I am basically looking for is to consume messages with a MessageListener
where in case of an unexpected error during message processing the onMessage()
method throws a runtime exception that eventually signals to the broker that
the message was not acknowledged. The broker then should try to redeliver the
message 3 times and then put it into a pre-configured DLQ.
I played around with all kind combination of session modes incl. qpid-jms
specific ones and different qpid-jms redeliveryPolicy settings but I am not
getting any further. For example when I set the session mode to
AUTO_ACKNOWLEDGE in qpid-jms, the message seems to be redelivered locally
indefinitely. When I use any other session mode the message is not consumed a
second time.
The Artemis JIRA issue contains a simple unit test case that can be used to
easily reproduce the problem I am having.

(https://issues.apache.org/jira/secure/attachment/12926230/Artemis1618_AmqpDeadLettering_Test.java)
I would really appreciate if someone could have a look at it and give me a hint
on whether this looks like a bug/limitation in qpid-jms, or if I am doing
something completely wrong, or if it seems to be a broker implementation issue.
Thanks!
Regards,
Johan
The JMS specification defines that an exception thrown from onMessage is
a programming error, so I'd say first thing to do is not do that any
more and go from there. The behavior you want sounds like a good
candidate for a transacted Session with configuration on the redelivery
policy that controls how many deliveries to allow before the message is
no longer allowed to be redelivered.
Documentation on the redelivery policy for the Qpid JMS client is here.
