I have had a similar problem with MDBs. My problem was that the resource is was referring to via the mapped name was not infact a QueueConnectionFactory but infact something completely different... the provider adapter. By correcting the mapped name, the problem was fixed. The exception / stack trace provided no guidance to solving this problem... only through trial and error did I realise the cause. In Response To: Hello, In a stateless EJB im using: | @Resource(name = "mail/localMail", mappedName = "Mail", shareable = true, type = Session.class) | private Session m_mailSession; | Trying to connect the Bean from a Client I got an NullPointerException. Im using JBoss-4.2.2.GA default installation without any changes Windows XP Any hints?
