Намучился я уже с этой явой, мочи нет)) уже истеричный смешок появляется, а вот постоянно появляется что-то такое что вроде бы элементарно, но не работает...
Так вот, к сути:
само приложение - JAVA-WEB - приложение
подключаю JSF
чуточку корректирую
добавляю класс сущности:
@Entity
public class userInfo implements Serializable {
private static final long serialVersionUID = 1L;
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private Long id;
private String login;
private String password;
public userInfo() {
}
public userInfo(String login, String password) {
this.login = login;
this.password = password;
}
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getLogin() {
return login;
}
public void setLogin(String login) {
this.login = login;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
Затем создаю сеансный компонент:
@Stateless
public class userInfoBean {
// @PersistenceContext(unitName = "MessangerPU")
// private EntityManager em;
public static final EntityManagerFactory emf = Persistence.createEntityManagerFactory("MessangerPU");
public static EntityManager em = emf.createEntityManager();
userInfo uInfo = new userInfo();
public Boolean findUser()
{
userInfo u = new userInfo("admin", "admin");
em.getTransaction().begin();
em.persist(u);
em.getTransaction().commit();
if (em.contains(u))
return true;
else
return false;
// return uInfo.toString().equals(u.toString());
}
ну и JAVA все нормально компилирует, развертывает и на строке
em.persist(u); велетает Exception без текста сообщения - что это значит? как исправить?
и да, я пользуюсь NetBeans 6.9.1
если нужен - то вот стек:
