[jboss-user] [EJB/JBoss] - Re: Are Stateless Session EJB Thread-safe

What you miss is that SLSBs *can* have internal state, e.g. a cached datasource handle that they re-use to serve incoming requests. Stateless is the interpretation from a client's point of view, so if a SLSB has 3 methods, a client should be able to call those methods on different bean instances, without that making any difference in the total outcome. The single thread guarrantee of EJBs makes writing those beans easy, so you don't have to think about concurrency issues. It also scales well as the server will create as many SLBSs as they are needed to handle the load. What you describe is a simple RMIServer singleton that must know how to deal with concurrent requests. That's a very different thing from EJBs.
