1) The exception stacktrace that you posted now is not the NameNotFoundException that you reported earlier :) 2) Going by the logs, it looks like you are deploying the EJB3 app as a jar and the servlet in a separate WAR. Nothing wrong with this. 3) The WAR contains your EJB interfaces (ex: the UserLocal). The EJB jar too contains the same interfaces. However both these deployments use different classloaders, which i guess is resulting in this error. We had a similar discussion about this sometime back.
