How to nicely destroy a topic being used?

[bugsbunny327]

Hello,

I am using Jboss 3.2.2. Server side I create at run time some topics and publishers. Subscribers are hosted by applets. When I stop my application I destroy all created topics.

All is working fine until I try to redeploy my application, with a running client (Subscriber). When I try to destroy a topic I got:

12:00:37,421 ERROR [TEST_TOPIC_1] Destroying failed
javax.jms.JMSException: The destination is being used.
at org.jboss.mq.server.JMSDestinationManager.closeDestination(JMSDestinationManager.java:807)
at org.jboss.mq.server.jmx.DestinationMBeanSupport.destroyService(DestinationMBeanSupport.java:142)

Ok why not except when I try after to lookup for the topic I got a NameNotFound Exception. Naturally if I remove all subscribers and publishers all is working fine.

Has anyone a suggestion?

Regards,

Pascal

Support for removing destinations with active subscribers has been added for 3.2.4
The subscriptions are closed before the destination is removed, instead
of throwing the exception you show.

We are having this same problem and it doesn't look like 3.2.4 (with the fix) is going to be relased. (I only see 4.0 beta.)

In any case it is often a serious decision to introduce instability by changing a product's release platform.

Does anyone know a workaround to clear out or close the existing subscribers on 3.2.3?

thanks,
Damon

To work around this, we kept a reference to the single TopicSubscriber and TopicSession used in conjunction with our topic and called close before calling destroy().
