Hi i posted a while agoabout signing java applets. With the help of you guys
my applet now works and is signed. Now i wish to write a java application
with a gui front end that can jar, sign and verify signed jars. are there
jar and signing libraries or will my front end have to shell the command
line commands, keytool, jar and jarsigner?
Since the volumes are so low, I think you would find spawning tools to
be an easier technique even if you did know how to recreate what they
do with standard libraries.
If you want to pursue that approach check out:
JarEntry
JarException
JarFile
JarInputStream
JarOutputStream
ZipEntry
ZipException
ZipFile
ZipInputStream
ZipOutputStream

You also might like to look into ANT for doing this.
Here is an ant script to compile, jar, and sign an applet. It also
builds a zip and copies files all over the place. You might tackle
instead a tool to generate and run an ant script for ant newbies.
