EJB delpoy Fehler

Question

Ich möchte meinen Krieg Archiv auf JBoss einsetzen, aber ich habe diesen Fehler:

ich versuche, es zu Google und es auf den gleichen Fehler von Internet-Lösungen zu beheben, aber ich konnte nicht beheben es. Ich bekomme diesen Fehler mehr und mehr.

Meine DAO-Schnittstelle:

/** 
* @Author is flystyle 
* Created on 05.06.16. 
*/ 
public interface IRequestDAO { 
    Integer createRequest(final Request source); 
    List<Request> list(final Date date); 
    List<Request> list(); 
    List<Request> list(final Station begin, final Station end); 
    Request getRequestById (final int id); 
    List<Request> getRequestsByUserId (final int userId); 

    void removeRequestById(final int id); 
    void removeRequestByUser(final User user); 

    @Deprecated 
    void removeAllRequests(); 

} 

Meine UserDAO Klasse:

} 

Klasse My Admin Controller:

@ManagedBean(name = "rails_admin_panel") 
@SessionScoped 
public class AdminPanelController implements AdminAction{ 

    private List<User> allUsers; 
    private List<Request> allRequests; 

    @EJB 
    private UserDAO userDAO = new UserDAO(); 
    @EJB 
    private RequestDAO requestDAO = new RequestDAO(); 

    public void viewAllUsers() { 
     allUsers = userDAO.getAllUsers(); 
    } 

    public void viewAllRequests() { 
     allRequests = requestDAO.list(); 
    } 

    public void deleteRequest(int id) { 
     requestDAO.removeRequestById(id); 
    } 

    public void deleteUser(int id) { 
     userDAO.banUser(id); 
    } 

    public List<Request> getAllRequests() { 
     return allRequests; 
    } 

    public List<User> getAllUsers() { 
     return allUsers; 
    } 
} 

Können Sie mir helfen?

Während des Start-App-Server kann Schnittstelle pro.alexfly.lab4.dao.UserDAO nicht finden, weil Sie niemanden haben. Um es zu beheben:

• Versuchen Sie IUserDAO hier eine Schnittstelle verwenden:

@EJB 
private UserDAO userDAO = new UserDAO(); 

• Sie Ihre eigene Instanz nicht manuell erstellen, sollte es von JBoss Behälter injiziert werden.
• Überprüfen Sie, ob Ihre Schnittstellen @Local Annotation haben.
