erreur create entité

**trin86** · 27/09/2009, 14h30

Bonjour à tous,

J'ai écrit un projet J2EE avec mes beans entités + un CRUD générique + une couche service où j'implemente les méthodes de chaque entité.

J'ai créé un projet test où je fais un create puis un find d'un meme objet.
Voilà les erreurs que j'obtient:

Il manque l'initialisation du DAO.

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

public class UserBean implements Iuser {
 
	private IGenericDao<User, Integer> IUserDao;

Je pense qu'il faut injecter le DAO avec l'annotation @EJB apres l'avoir defini en tant que session bean avec une interface locale.

**trin86** · 28/09/2009, 09h34

svp est ce que c'est possible d'utiliser une seule interface générique pour tous les CRUDs session de tous les objets et faire le remote vers cette interface.
merci

OUI, finalement c'est possible.
Maintenant lors du déploiement je rencontre un autre bug au niveau de sql, voici l'affaichage de la console server:
