Question

Я получаю сообщение об ошибке при попытке сохранить сущность из класса. Я создал класс UserController, и когда я пытаюсь выполнить метод Register, в строке em.pertist (usr) появляется ошибка, когда я запускаю этот код внутри UserRegBean напрямую, он работает ... Кто-то может помочь мне, пожалуйста ...

Вот код:

UserController.java

public Boolean Register(String _userName,String _passwd) throws NoSuchAlgorithmException, UnsupportedEncodingException

    {

         User usr = new User();

         usr.setEmail(_userName);

         MessageDigest digest = MessageDigest.getInstance("SHA-1");

         digest.reset();

         digest.update(pwdSalt);

         byte[] input = digest.digest(_passwd.getBytes("UTF-8"));    

         BASE64Encoder encoder = new BASE64Encoder();

         usr.setPassword(encoder.encode(input));

         em.persist(usr);



        return true;

    }

UserRegBean.java

public void register() throws Exception {

      UserController uControl = new UserController();

          Boolean registered = uControl.Register(this.email,this.passwd);  



/*             User usr = new User();

             usr.setEmail(this.email);

             MessageDigest digest = MessageDigest.getInstance("SHA-1");

             digest.reset();

             digest.update(pwdSalt);

             byte[] input = digest.digest(this.passwd. getBytes("UTF-8"));    

             BASE64Encoder encoder = new BASE64Encoder();

             usr.setPassword(encoder.encode(input));

             em.persist(usr);*/

       }
