Récuperation des donnees pour une formulaire
Bonjour, je suis en train de developper une application entreprise avec JEE. C'est choisi de travailler avec netbeans 6.7 . J'ai choisi encore le framework JSf et la base de donnees MySQL . Le projet est composee d'une premiere page pour le login ou la creation d'un nouveau compte .Une deuxieme pour l'acceuil qui contient un lien "modify" vers une troisieme page pour la modification des donnees entrees precedemment dans le formulaire et enregistrees dans la base de donnees .J'ai voulu faire de tel sorte que les anciennes informations de l'utilisateur enregistrees dans la base de donnees soinent affichees dans les champs de la formulaire pour modifier ce qu'on veut et laisser ce qu'on veut .
Le code du page bean metier est le suivant :

Pour le faire j'ai utilisé la declaration suivante
Code:
value="#{metier.c.cams}"
comme value mais j'ai rien obtenue dans les zones de texte inputtext .
J'ai rien mis dans la methode Update dde la page metier car j'ai voulu tester avant .
je sais pas si j'ai fait le bon choix ?Mais j'espére trouver ici la solution .
Merci d'avance .
