Hi Guys,
I've configured JMS to use JDBC persistence and I send JMS messages in
DUPS_OK_ACKNOWLEDGE mode to make sure that the messages are guaranteed. I use the
following code to enforce this when I send the message.
queueConnection.createQueueSession(true, Session.DUPS_OK_ACKNOWLEDGE);
queueSender.setDeliveryMode(DeliveryMode.PERSISTENT);
The deployment descriptor for my Message Driven Bean is as follows:
<message-driven >
<description><![CDATA[This is reponsible for prioritising requests and dispatching
them accordingly.]]></description>
<ejb-name>QueueDispatcherMDBBean</ejb-name>
<ejb-class>com.pindartech.imageprocessing.manager.queuemanager.QueueDispatcherBean</ejb-class>
<message-selector></message-selector>
<transaction-type>Container</transaction-type>
<acknowledge-mode>Dups-ok-acknowledge</acknowledge-mode>
<message-driven-destination>
<destination-type>javax.jms.Queue</destination-type>
</message-driven-destination>
</message-driven>
I have absolutely no complains in this configuration and it works fine when things
happen normally. But when I abruptly bounce JBoss using (Ctrl + C) and restart it
again, some times (not always), I tend to loose one JMS message per abrupt restart.
Since I've configured in DUPS_OK_ACKNOWLEDGE mode, I expect app server to resend the
notification even in exceptional scenarios. In my MDB, I do the following.
public void onMessage(javax.jms.Message message) {
try {
// do the business...
} catch(Exception e) {
this.messageContext.setRollbackOnly();
}
}
Should I propagate the exception up the onMessage() call instead of just rolling back
the Transaction in my MDB ?
Is there another way to shutdown JBoss other then (Ctrl + C) so that abnormal
scenarios in my application does not happen ?
Your advice is much appreciated. Thanks in advance,
Magesh
