Hi guys, I came accross the same problem. What I saw is that it doesn't matter if your remote object are using the @service annotation or just @remote. As long as the configuration is set to anything else then "ports-default" (example ports-01, see earlier post) then JBoss 4.0.4GA is not able to execute any kind of function on any remote object (in my case stateless session bean). On the client side you end up with the earlier in this thread posted exception. If you set the configuration to ports-default, everything works fine. We would be realy glad if this bug is resolved as fast as possible. A patch release before RC9 woudl be great.
