Mais j'ai un message d'erreur qui dit:

message

descriptionThe requested resource () is not available.
GlassFish v3

Apparemment la classe Connecter.java est introuvable.

Merci

**Bdloul** · 27/03/2012, 14h43

Le web.xml?

**tchize_** · 27/03/2012, 14h49

1) ton annotation WebServlet est commentée -> elle ne sera jamais lue. Décommente la
2) tu mappe sur /Connexion mais dans ton formulaire tu vise /Connecter, ce n'est pas la même chose.
