Jamie, what I was saying is that: 1. If you don't use http session clustering, you can remove tc5-cluster.aop from your deploy directory and use your own jboss-aop.xml. That should work. 2. If you do, you will need to include tc5-cluster.aop in your classpath. Furthermore, you will need jboss-aop-aspect.jar (for aop aspects) in your classpath as well during compilation.
