title: Signing Jars using signtool
body: <p>I am trying to sign 3rd party jars using signtool on solaris.  The jars already have a manifest.mf file, but signtool creates a new MANIFEST.MF file in the META-INF/ directory and uses that to sign the jar.  If I try to validate the signed jar, it fails because there are two different version of the manifest file.  If I copy what is in the current manifest.mf file to a MANIFESET.MF, signtool overwrites the data. </p>
  
  <p>Is there anyway to specify what file to use to sign the jar (e.g manifest.mf over MANIFEST.MF)?  Or is there a way to tell signtool what to include in the new MANIFEST.MF?</p>
  
  <p>This is a pressing issue since next update of java requires jars to be signed as well as include the permissions tag for applets.  </p>
