sur eclipse elle marche bien.
quand je veux l'integrer dans une page html :

<html>
<body>
<applet code="Toto9.class" archive="jfreechart-1.0.9.jar,jcommon-1.0.12.jar,Toto9.jar" width="500" height="500">
</applet>
</body>
</html> |
sachant que :
jfreechart-1.0.9.jar,jcommon-1.0.12.jar,Toto9.jar sont dans le meme repertoire que la page html .
quand je lance la page html :
dans la console java :
error format "incomaptible magic value" .
je suis sous linux .
l'applet est signé .
comment configurer une applet qui necessite des jars ?
Merci
