  |     if (languageID == null) {
  |       em.persist(user);
  |       return user.getLanguage();
  |     } else {
  |       return em.find(LanguageEntity.class, languageID);
  |     }
  |   }
  | }
  | 
The above code produces a NullPointerException on "If (userBean.findByUserLogin(userLogin).size() <= 0)" because userBean is null.
Shouldn't a reference to UserEJB be injected there or am I missing something?
