Erreur de configuration JSF ejb3 et richFaces
bonjour, je dois réaliser un site web en J2EE dans le cadre de mes études.
J'ai choisit d'utiliser Seam-gen afin de me créer un projet eclipse qui me permet d'utiliser le framework JBosse Seam avec JSF, EJB3 et la persistence avec JPA.
J'utilise une base de donnée MySQL 5.0.
J'ai réussi à créer le projet sans difficulté. Lorsque que je lance le serveur JBoss, aucun problème, mon projet fonctionne puisque je peux voir une page de présentation sur le navigateur.
http://localhost:8080/reference/home.seam
Lorsque je décide de développer mon site je rencontre des erreurs de config (enfin je pense) dont je suis incapable de résoudre.
J'ai commence par créer le login :

je ne vois pas trop le problème. Je n'ai pas touché les fichiers de configuration (Web.xml ....) puisque tout est bien configuré en utilisant seam-gen (mais bon biensur rien n'est sur...).
