Erreur JPA sous glassfish
Bonjour tout le monde, je viens vers vous car j'ai une erreur lors du remplissage d'un de mes selectOneMenu.
Mon objectif serait d'importer des données de ma base de données puis de les afficher dans mon selectOneMenu.
Il m'affiche un problème mais je ne vois pas quel est le problème, quelqu'un pourrait m'aider je vous prit.
Voici mon code xhtml :
