Tutoriel de Serge Tahe Java EE5 : des soucis avec la couche metier

**babacamara** · 04/07/2014, 15h47

Bonjour à tous
Je suis le tutoriel de Serge Tahé:Introduction à Java EE 5 a l'adresse suivante http://tahe.developpez.com/java/javaee/ mais des j'ai des soucis a l’implémentation de la couche métier. J'ai déjà teste la couche Dao, elle s’exécute bien.

L'interface de la classe métier et sont implémentation sont les suivantes:

Bonjour,
L'erreur est une violation de cette contrainte :

Code :

@ManyToOne(optional = false)
    private Indemnites indemnites;

. Tu essaies de créer un Employe avec une indeminité nulle, alors que l’indemnité en question ne doit pas être optionnelle.
