Récupérer liste d'éléments persistés

**GiZeus** · 02/06/2011, 16h31

Bonjour à tous !

Je suis sur un projet wicket et je fais pour l'instant persister des éléments à l'init. Pour tester la récupération d'un de ces éléments je lance la méthode "findClientEntities()", qui doit me retourner une liste de toutes les entités .Seulement ça merde et j'ai un joli message d'erreur :

La DAO est générée par Netbeans, je n'ai qu'à créer les pojo annotés pour lui dire quoi faire. Je vous mets ci-dessous le persistence.xml, la classe Client et son contrôleur DAO :

Je suis en Java EE 6, choix effectué en raison de la DAO générée dans cette version.

Merci d'avance pour votre aide.
