| @PersistenceContext
| private EntityManager em;
|
| @In
| private transient Context sessionContext;
| @In
| private transient FacesContext facesContext;
|
| public boolean authenticate() {
| facesContext.addMessage(null, new FacesMessage("authenticate"));
| List<User> results = em.createQuery("select u from User u where userName=:username and password=:password")
| .setParameter("username", identity.getUsername())
| .setParameter("password", identity.getPassword())
| .getResultList();
|
|
| if ( results.size()==0 )
| {
| facesContext.addMessage(null, new FacesMessage("Invalid login"));
