Signed jar files

Posted on 2004-04-06

I have some jar files that were signed by a previous developer., and I have signed them too. When I tried to load the jar files through Java Web Start, it complains of more than one certificate has been used to sign the resources.

Is there a way to either remove the signature of the previous person or just unsign the whole jar file?

re-jar it.
ie. unjar it, and create a new jar with the contained class files.
