Hello all,
I have some Signed Jar files.Now I have to insert my own jar file into the already existing jar files .Obviously my Jar file is not signed so it will not work.
I do not have the signature used to sign the existing jar files
Is there any way that i can sign my jar file using the existing jar files?
Is there any other way?


Please Help

You need the certificate with which your signed jar files were signed. You cannot sign your jar file with a signed jar file. That would defeat the purpose of signing, as it would mean that you could download a jar file signed by say Sun Microsystems and then create your own jar files---containing, say, a virus---signed by Sun Microsystems.

Are you creating an applet, a Java application deployed by WebStart or something else?
