Maybe not the right way to go about this (bumping up this old thread) but I've got things working -- mostly. There's one big thing that still nags me: Is it possible to send unchanged references (just references, not the associated objects) back and forth using metadata? Or an alternative that's close? I've been trying a few things to make it work but couldn't really. Most of the time it gives a marshalling error (the dispatcher is not serialisable). When I tried doing the rmi stuff so it sends a stub I got another obscure error. Besides, sending back a marshalled stub is not all that useful probably. I would think it's possible since that's basically what the proxy-invoker does to select which container to invoke, right? thx :) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4035766#...
