I have very fundamental problem with EJB3 and may be with EJB at all. I need setup beans conversation in session. Is it possible to create pattern when several SfSB collaborate with each other in session and keep their state? That means : Bean A has reference to beans B and C, B has reference to C and A, C has reference to A and B. They must share some object to do that? Have you some idea? Thanks.
