I have a problem with injection of EntityManager in my Authenticator class. When I login my EntityManager variable is null and I get NPE. In my environment I'm using jboss-4.0.5 and JSF 1.2 RI. I'm wondering if my authenticator class shouldn't be SFSB or SLSB in this case?

Here is part of my Authenticator class:

@Name("authenticator")
public class Authenticator {

 @Logger
 Log log;

 @Out(required = false, scope = SESSION)
 private User user;

 @PersistenceContext
 private EntityManager em;

 public boolean authenticate(String username, String password,
 Set<String> roles) {
