I'm running JBoss 3.0 and trying to do a simple comparison between it and other app servers on distributed EJB transactions. I have a client EJB (SLSB) on one engine which invokes a service EJB (SLSB) on another engine. The two engines are completely standalone (i.e. not clustered). The client EJB is simply a delegator, the service EJB just builds an array of String and sends it back.

When I use the client EJB to access the service EJB, it throws a java.rmi.MarshalException, with a nested exception of: java.io.NotSerializableException: org.jboss.tm.TransactionImpl. If I access the service EJB directly with a standalone client, I'm able to use it without any problems. So, I know there's no problem with serialization within my EJB. It appears that JBoss doesn't support this type of distributed transaction. Any suggestions?
