Yes, you arrived at the solution. Here you have: @Local({CallHandlerService.class}) | @Remote({CallHandlerService.class}) Which your version of JBoss has allowed, but in fact this is prohibited: "EJB3 Core Specification 4.6.6" wrote : The same business interface cannot be both a local and a remote business interface of the bean. I can't find the JIRA for this at the moment, but it's been fixed and now cites an error on deployment.
