Afficher des slides sur une page JSP

**Zenight** · 14/08/2014, 14h20

Bonjour,
Ca fait 3 mois que je suit un stage en informatique. Mon objectif est de faire une application permettant de donner des informations complementaires a un Powerpoint.
Au debut ca marchait bien, et j'avais reussi a faire une application en IHM Java operationnelle.

Mais les choses ont commencés a se corser lorsque mon maitre de stage a suggere de faire cet application en format web, et donc d'utiliser du JEE.

Ca fait donc une semaine que j'essai de faire marcher tout ca. Ce qui etait operationnel dans l'IHM ne l'est plus ici. Je n'arrive meme pas a detecter la source du probleme, c'est pourquoi je viens vers vous pour demander de l'aide, en tant que dernier espoir.

Ma servlet

Voila voila. Je commence un peu a paniquer car je dois finir ca pour la semaine prochaine, et que sans ca je suis bloqué. Comme je l'ai dis je n'arrive pas a comprendre d'ou vient l'erreur, surtout que sur une autre plateforme ca marchait correctement !
Je crois que j'ai deja passé chaque ligne du message d'erreur en recherche google, sans succes

Merci d'avance, et si vous avez besoin d'infos supplementaires, n'hesitez pas !

(ps : desole pour les accents, je suis sur un clavier qwerty...)
