Problème Vaadin - Connection à la base de données avec Wamp

Bonjour à tous,

Je suis un nouvel utilisateur de Vaadin (version 6) et j'ai de gros problèmes pour faire cohabiter Wamp (pour Mysql) et Tomcat.

J'ai changé le port pour le serveur Wamp, j'ai mis à la place du port 80 le port 82.

J'ai donc une classe nouveau qui contient la partie principale de mon code :

Mais voilà quand je lance mon application, j'obtiens ce type d'erreur :

Pièce jointe 149391

Quelqu'un aurait t-il une idée de la source de cette erreur, et pourrai m'éclairer sur la configuration à adopter pour se connecter à Wamp pour Mysql en lançant une application avec un serveur Tomcat. Je ne sais pas si l'erreur vient de mon code ou de la configuration de mes outils.

Merci d'avance,
