Probleme avec JSF
Salut
je développe une simple application web avec JSF sur netbeans 6.8.
Dans la page d'accueil il faut entrer le nom d'utilisateur et le mot de passe pour accéder à l'autre page web (si le d'utilisateur et mot de passe sont valide on accède à la page "welcomeJSF.jsp" sinon "error.jsp") le problème est que je n'arrive pas à accéder aux autres pages chaque fois que je clic sur le boutton"submit" une message d'erreur s'affiche, et je n'arrive pas à trouver l'erreur
SVP aidez moi je suis une débutante
voici le code source
user.jsp
