Netbeans 7- JEE- Maven- Controler d'Entité- compilation avec dépendances

**tralloc** · 15/02/2011, 16h59

Bonjour,
Je ne sais pas si je dois publier ici ou dans JEE...

Je voudrais tester la création d'un EAR sous Netbeans 7.0 et j'ai voulu tester cela avec un petit tutoriel.
la première étape est de créer le projet, (pas de problèmes) d'ajouter les bonnes librairies avec maven, pas de soucis, tout compile.

- Dans le sous projet qui concerne les EJB
J'ai importé les tables du sample contenu dans la base derby sous forme d'entités.
Ca marche ça compile, pas de soucis.

Ensuite j'ajoute les objets façade (clic droit sur une partie de mon projet, nouveau, "Session Beans for Classes", cela me crée une classe abstraite utilisant les templates et des objets Facade demandés.

Alors quand je compile pas de soucis avec le bouton "compiler et nettoyer", cependant si je fais "Construire avec les dépendances j'obtient un message d'erreur.

Voici mon AbstractFacade:

Si je construit le projet en enlevant la classe abstraite et en remplaçant par du code classique je n'ai pas de plantage. Malheureusement on perd le bénéfice de l'héritage et des génériques.
