A new JNDI lookup to a SFSB will always result in an reference to invoke on a new, fresh instance. What do you mean by "correct"? I don't think this issue here is your JNDI config. :) Try again with doing one lookup, placing that stub in the HttpSession, and paste your code if you're still having problems?
