[jboss-dev-forums] [Design of Messaging on JBoss (Messaging/JBoss)] - How to obtain getMessageCounters for a Topic

[leonv]

>From my application I?m publishing messages to the testTopic topic. 
This application is not running under Jboss.

Does anyone know how I can obtain the Message counters ... getMessageCounters() for a given topic?
See:

http://labs.jboss.com/file-access/default/members/jbossmessaging/freezone/docs/javadoc/api-1.4.0.CR1/org/jboss/jms/server/destination/TopicService.html#getMessageCounters()


As base I'm using the out of the box jboss-4.2.1.GA installation without ANY configuration change.

In the file:
\jboss-4.2.1.GA\server\default\deploy\management\console-mgr.sar\web-console.war\TopicSubscriptions.jsp
Is almost what I needed.
Almost since this page return exceptions.
(If it works I can reformat the output to XML)

Try:
http://localhost:8080/web-console/TopicNavigation.jsp?ObjectName=testTopic

And click subscriptions.

If JMX is the only solution, does somebody has a piece of example code?

Thanks for any help
