Donc ça se passait plutot bien dans Netbeans (5.0) mais dès que je veux tester dans une page html sa plante...
Voila mon code :

Ce que je comprend pas c'est que dans le texte de l'erreur on ne parle a aucun endroit de code a moi... Peut-etre un probleme de version, d'inclusion de librairie...?
Si quelqu'un a une idée ça serait super sympa....
Merci[/code]

Tu as visiblement réalisé to applet avec Matisse, il faut donc, à l'éxecution rajouter le jar swing-layout-1.0.jar que tu trouveras quelque part dans le répertoire d'install de NB.

Merci bcp valered, problème résolu en ajoutant le jar que tu m'a indiqué, qui chez moi se trouve ici : C:\Program Files\netbeans-5.0\platform6\modules\ext\swing-layout-1.0.jar

Mon applet marche très bien maintenant,
encore merci
