1. Backing bean :

  | @Name("authenticator")
  | public class Authenticator {
  |     // logger instance
  |     @Logger
  |     Log log;
  |     // Seam Identity Session Bean For User Identification
  |     @In
  |     Identity identity;
  |     // UserName Fro Session Context.
  |     private static final String USER_VAR = "currentUser";
  |     // Session Context
  |     @In
  |     Context sessionContext;
  |     // Database Entity Manager
  |     @In(value = "#{entityManager}")
  |     EntityManager em;
  |     // Faces Messages
  |     @In
  |     private FacesMessages facesMessages;
  | 
  |     public boolean authenticate() {
  |         try {
  |             facesMessages.clear();
  |             log.info("authenticating = " + identity.getUsername());
  |             List<Users> users = (List<Users>) em.createNamedQuery("Users.findByUserName").setParameter("userName", identity.getUsername()).getResultList();
  |             if (users == null || (users != null && users.isEmpty())) {
  |                 facesMessages.addToControl("username", "User #{user.username} does not exists");
  |                 //FacesMessages.instance().add("User #{user.username} does not exists");
  |                 return false;
  |             } else {
  |                 for (Users user : users) {
  |                     byte dbpaswd[] = user.getUserPwd();
  |                     String strpwd = identity.getPassword();
  |                     MessageDigest md5 = MessageDigest.getInstance("MD5");
  |                     md5.reset();
  |                     md5.update(strpwd.getBytes());
  |                     byte[] userpasswd = md5.digest();
  | 
  |                     boolean result = MessageDigest.isEqual(userpasswd, dbpaswd);
  |                     if (result) {
  |                         identity.addRole("admin");
  |                         sessionContext.set(USER_VAR, user);
  |                         return true;
  |                     }
  |                 }
  |             }
  |             facesMessages.addToControl("password", "Incorrect Password For This User");
  |             //FacesMessages.instance().add("Incorrect Password For This User");
  |             return false;
  |         } catch (Exception e) {
  |             e.printStackTrace();
  |             facesMessages.add("Could not login. System Error");
  |             //FacesMessages.instance().add("Could not login. System Error");
  |             return false;
  |         }
  |     }
  | }
  | 
  |
