I am trying to use a (remote) jboss-messaging 1.0.5SP1 from within a Seam application (2.0.2SP1). I cannot upgrade JBoss or JBoss Messaging at this moment (there are many applications talking to that messaging server, upgrading would mean a lot of work).
The problems I encounter are with classloading. I tried a 'scoped deployment', but run into errors concerning the javassist:
java.lang.ClassCastException: nl.mypackage.User_$$_javassist_9 cannot be cast to javassist.util.proxy.ProxyObject
This is after putting the same javassist.jar in the (scoped) jboss-messasing.sar. With the default javassists, I get method not found errors in the ProxyFactory class.
I also tried putting all the jboss-messaging client jars in the ear file, but this gives other problems with the initialization of the 'aop on the client side'.
Is it even possible what I am trying to do, or should I give up at this point (and wait for an upgrade of all the other applications)?
All tips are welcome!

Earlier versions of JBM had some issues with scoped deployments, which were fixed in later versions.
Have a look in JIRA to see the issues and in which versions they were fixed.
