ZipException : error in opening zip file
Salut tout le monde,
j'ai besoin de creer un fichier zip en Java. Je dois zipper le contenu d'un repertoire (fichier + sous-repertoires). J'utilise une fonction recursive.
Mon fichier zip est bien creer, lorque je l'ouvre/le decompresse avec winrar, winzip, tout marche bien, idem en ligne de commande sous linux (unzip).
Le probleme est que j'ai besoin de reouvrir ce zip en java, et la c'est le drame:
Code:

at java.util.zip.ZipFile.<init>(ZipFile.java:203)

Voila le code de ma fonction:

L'exception est levée sur la ligne:
Code:
ZipFile zip = new ZipFile(zipFile);
Est-ce que vous voyez quelque chose qui vous parait bizarre?
Je suis sur ce probleme depuis plusieurs jours et la je desespere...
Merci,
Phil
