Bonjour,
J'utilise la librairie PDFBox pour ouvrir un document PDF. Ce document s'ouvre avec un mot de passe. J'utilise le code suivant pour ouvrir le document et le décrypter à l'aide du mot de passe.
JE recois l'erreur suivante lorsque j'essaie de l'ouvrir (alors que le mot de passe marche quand je j'essaie d'ouvrir le fichier normalement) :
Exception in thread "main" org.pdfbox.exceptions.CryptographyException: Error: The supplied password does not match either the owner or user password in the document.
at org.pdfbox.pdmodel.encryption.StandardSecurityHandler.decryptDocument(StandardSecurityHandler.java:230)
at testPDF.ExtractText.main(ExtractText.java:216)
J'espere que quelqu'un pourra me dépanner parce que j'ai vraiment beaucoup de mal à comprendre !
Merci d'avance
Voila le code que j'utilise (qui est le code présenté dans le zip de PDFBox... )
