I am trying to use Hermes 1.8 with JBOSS 3.2.3 and have run into the following problem.
I have setup classpath group successfully.
I have setup context successfully.
I have created a session successfully.
I have discovered queues/topic (15) successfully.
WHEN I try to view a queue or a topic I am getting the above error.
Please advise!
TIA

At a guess, and I've not tested with JBoss 3.X, its a JMS 1.0.2b vs 1.1, its likely a topic/queue domain issue.

Ensure the type of connection factory is queue or topic and then ensure u only try and use queues or topics on the correct factory - I think JBoss 3.X is strictly JMS 1.0.2b. Look in the Preferences->Sessions panel.

The JMS API is the standardized interface to a JMS provider, sometimes called a Message Oriented Middleware
(MOM) system. JBoss comes with a JMS 1.0.2b compliant JMS provider called JBoss Messaging or
JBossMQ

You are right about the jms specs impl. Let me test your theory and get back to you. Thanks for the reply.

It works! Thanks.

Cool, I'll update the code so we get a better error message next time!
