Jan, I appreciate the response but I don't want to replace, I want to append or prepend depending on situation which requires reading the manifest Class-Path and appending to it. Then it could be replaced. The manifest has to be read first. Your procedure of unjar, replace, jar does not take into account what was already in the manifest... it just overwrites it.
I'm still looking for a solution unless I'm just too blind to see ;> Thanks, Bill -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Sent: Friday, May 14, 2004 7:34 AM To: [EMAIL PROTECTED] Subject: RE: Is there a way to update the Class-Path in a manifest? <unjar> <replace> / <replaceregexp> <jar> Basically you are not aware of any manifest-specific thing. You extract a text file, modify it and write it back.
