<div class="jive-rendered-content"><blockquote class="jive-quote"><p>jaikiran pai wrote:</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>2) The meaning/usage of DLQ : In HornetQ, there are just Dead letter Addresses. But from the point of view of a JMS client (like MDB) which are just aware of (JMS) queues and (JMS) topics, how would the MDB subscribe to a dead letter (JMS) queue. I am still looking at the hornetq configs in AS and reading through the docs to see how the (hornetq) DLA is being setup. I guess, there needs to be some layer which sets up a (HornetQ) queue subscription to the DLA to make it look like the (JMS) DLQ.</p></blockquote><p>We can stop worrying about this part now, because the reason why the DLQ/DLA is <em>not</em><span> being triggered for the MDB, is because of this bug/config issue in HornetQ </span><a class="jive-link-external-small" href="http://community.jboss.org/message/537970#537970" target="_blank">http://community.jboss.org/message/537970#537970</a></p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>I quickly hacked the MessageReference#getDeliveryCount() impl to return a value higher than the max-delivery-count and I could see that the message is redirected to the DLQ and the EJB3 test passes. So it's just a matter of fixing that issue mentioned in the other thread.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>As for the other questions raised in this thread, they are still valid.</p></div>
