    Using @Resource causes NPE at org.jboss.ejb3.JndiUtil.lookup

    Georg Sendt Newbie

      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?

      Regards,

      Georg
