Erreur "javax.ejb.EJBException"

**Linos1003** · 08/02/2012, 14h17

Bonjour,

J'utilise l'utilitaire de génération des pages JSF CRUD de NetBeans 7.1 à partir d'un SGBD Postgres.

La génération se passe bien mais lorsque je lance l'application web j'obtiens l'exception suivante:

Quelqu'un saurait-il me dire d'où vient le problème ?

Merci d'avance pour votre aide.

A mon avis t'es en train de faire un mélange de requêtes natives et requêtes objet dans la même requête. Peut-on voir ton entité Distributeur ?
Quel type de requête veux tu faire ? Du natif ou objet ? Peut-on voir comment invoques tu ta requête ?

Et laquelle des NamedQuery as-tu invoquée? peut-on voir le bout de code lançant la requête?

En fait, je l'ai invoqué à partir d'une page JSF.
Voila la page, dès que je clique sur le lien qui l’amène, l'exception se déclenche.
