Dwin is right. WS-Addressing is the right way to build conversational web services. Take a look at the user guide and the corresponding samples. It contains an example for a staful service. It's already supported for quiet some time now: http://labs.jboss.com/portal/jbossws/user-guide/en/html/wsaddressing.html IMO passing the serialized handle around is not a good idea. I could picture a SLSB facade instead that keeps a UUID->Handle registry and delegates to the SFSB beans behind the scenes. You could hand out the UUID using WS-Adressing and internally rely on the ejb handle. You could even offer a simple API for clients to resign from their sessions.
