Erreur incomprehenisible d'où ca vient ?

bonjour a tous.
quand je crée une classe simple avec connection sur mysql et execution de requete ca marche nikel!ts ça dans le meme projet!mais quand je fais une page JSP ca plante! ca m'envoie le code juste en bas: ya t'il qqchose de plus dans le parametrage de eclipse pr JSP: le pilote JDBC est bien inclu sinon la classe de test a part aurait pas marché!
Merci.
