Signature Applet

Bonjour,

Je suis entrain de develloper un formulaire qui genere un PDF.
Sur le PDF, j'aimerais faire apparaitre la signature du benificiaire. Il faut donc une zone de saisie en JAVA pour la souris ou un stylet puisse créer la signature.

J'ai trouvé un code qui permet de faire ceci :

SIGNPAD/

Ce que j'aimerais, c'est qu'il enregistre la signature en format JPEG comme il est sensé le faire mais helas, cela ne fonctionne pas.
J'ai aucune connaissance en JAVA, je developpe un peu en HTML/PHP puis de l'AutoIT.

Je viens vers vous pour essayer de me donner un coup de main.
Voici le code de l'index :
