opérations CRUD sur plusieurs entity
Bonjour je développe une application avec JSF et JPA(Netbean6.5.1 et glasfishv2 et PostgreSQL 8.4.1 comme serveur de base de données). Je joins une partie de la db. Un customer peut être lié à plusieurs listes et inversement. un Customer peut être propriétaire ou bénéficiaire d'une liste.(désolais pour ce franglais:zoubi:).
Je fais une recherche des listes et j'aimerai afficher les champs suivants: Nom et Prénom de l'entity Customer, le type de l'entity Type, la date de événement et le statut de l'entity ListCadeaux. J'arrive à afficher tous les champs sauf ceux du Customer. Ca doit paraitre simple mais, mais je tourne en rond. :calim2:
Quelqu'un a t-il une piste merci d'avance.
voici les entity
