[jboss-user] [JBoss Messaging Users] - Exception when trying to get ConnectionFactory

[sacauskis]

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: javassist/NotFoundException
