seam.properties:

And finally our LoginAction class:

  | import javax.persistence.PersistenceContext;
  | 
  | import model.User;
  | 
  | import org.jboss.seam.annotations.In;

  | import org.jboss.seam.annotations.Out;
  | 
  | import org.jboss.seam.log.Log;
  | 
  | @Stateless
  | @Name("login")
  | public class LoginAction implements Login
  | {
  |    
  |    @In 
  |    @Out
  |    private User user;
  |    
  |    @PersistenceContext
  |    private EntityManager em;
  |    
  |    @Logger
  |    private Log log;
  | 
  |    public String login()
  |    {
  |        
  |        User u = em.find(User.class, "pasmith");
  |
