au niveau des SelectOneMenu je voudrais les remplir avec les informations contenues dans la table sessionexam mais lors de la validation du formulaire ne récupérer que l'id de la session d'examen choisie.

Lors de l'exécution du formulaire j'ai cette erreur: Erreur lors de l’injection de ressources dans le bean géré «sessionexamMbean»

Je travaille sous Netbean 8.0RC et j'utilise Glassfish comme serveur d'application.

Merci d'avance pour toute contribution

Bonjour,

ce serait bien d'avoir l'EJB qui va avec.

D'après le message d'erreur il ne trouve pas le NamedQuery findAll

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

Caused by: java.lang.IllegalArgumentException: NamedQuery of name: findAll not found.

Remplir un SelectOneMenu avec le contenu d'une table de base de données
