Hi fellows, I hope I've picked the right forum for my question! I have seen lots of examples about using an EJB3-based Application as a Server (e.g. Service) for another java-based Client-Application. But I can't find any example about using a J2SE Application as a Server for an EJB based Application. Let me explain: I'm currently trying to build a SEAM/EJB3 based Web-App which needs to interact with a Service located in a J2SE Application. My first attemp is to connect these 2 Application by using the RMI. However this does not se(a)em to work. On the client-side I always get the shortened ClassNotFound-Exception listed below. I don't think that this is a real RMI/Security issue. My question is: did I do the right thing by trying to integrate RMI in a SEAM/EJB3-Application or is there another Approach which I should use but I currently don't know? Any suggestions are welcome!
