Clusting and JMS Topic

I posted this in the J@EE forum yesterday but got no replies so I was wondering whether you guys could help.

I am currently using WebLogic to cluster an application which makes use of JMS queues and topics. The queue behaviour is fine, however, I'm having a problem with the topic behaviour.

Say we have two cluster nodes and a topic which we publish a message to. The application is deployed in both cluster nodes and it recieves the message in each node, which is not the required behaviour. Is there any way to tell Weblogic that this application is actually a single clustered application and so should only recieve the message once?

Also, do you know of any good information on the web regarding the problems with clustering and JMS topics?

It is sorta covered in the JavaRanch Style Guide.
