Bonjour
J'essaie de modifier un applet java (je n'y connais rien) par modifs successives
L'applet est en .class
J'ai télécharger un décompileur (DJ Java Decompiler)
Jusque là tout va bien, mais maintenant je dois recompiler .... et je ne sais pas comment faire ?
Y a-t-il un Logiciel à télécharger ?
Ou puis-je copier l'applet décompiler dans ma page html ? si oui : où la mettre (je pense dans la balise "head" mais j'en suis pas sûr) ? et que dois modifier dans le texta pour que cela fonctionne :
Applet décompilée :

En fait ce que je veux faire c'est supprimer le background, ou l'avoir transparent .... peut-être n'est-ce pas possible
Si vous pouviez me répondre pour m'aider, ce serait hyper sympa
Merci d'avance
