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
