signtool

The application used to sign Applets to get them bypass the security restrictions of the Netscape 4.7 sandbox. It is so longer supported. Use jarsigner instead. The fool thing won’t just sign an existing jar file. You have to take your existing jar apart into separate files, sign it, and let it recreate the jar file. Beware: the signtool -m option uses an incompatible format for the *.mft files from jar.exe. Your mft file needs a lead + sign on its entries. e.g. + Main-Class: com.mindprod.Wassup.Wassup You will need a batch script something like this:

One nice thing the -G switch will do is let you create a temporary untrusted signing id that is not backed by a certificate signing authority, but that lets you get on with coding while you wait for your real one to arrive. You would use it like this:

jarsigner is the Sun JDK 1.3+ analog of signtool.
