Clebert
Thank you for your response
In jboss-4.2.2.GA/server/messaging/deploy/jms-ds.xml , I set
<use-java-context>false</use-java-context>
and i was able to successfully use JmsXA
However
1. Enqueuing 100 messages with the implementation that i posted at the root of
this thread-post takes 6 seconds
2. I also used JmsTemplate with JmsXA and got the same results
3. Then following your advice, i implemented the following and it took 7
seconds to enqueue messages (enqueuing loop below)
So i am concerned about the performance which are not in line with
http://www.jboss.org/file-access/default/members/jbossmessaging/freezone/docs/userguide-2.0.0.alpha1/html/performance.html
Am i doing something wrong? Where can look into to investigate the problem?
Thanks a lot for your advice
