Description

I have implemented a Service that uses conversations. The interface is annotated with @Conversational, the implementation is annotated with @Scope("CONVERSATION") and has a member protected String conversationId annotated with @ConversationID.

The Service runs fine when using binding.sca or binding.ws. If I use binding.rmi I get the following exception:
