I have this simple program to use JMS. When it runs:
TopicConnectionFactory tcf = (TopicConnectionFactory)
context.lookup("ConnectionFactory");
I get an exception:
Exception in thread "main" java.lang.NoClassDefFoundError:

I'm running jboss4.2.3GA and F:\jboss-messaging-1.4.5.GA on windows XP.
Thanks for any help you can give.
