how to call other jar files from current jar?

I try this:

Main-Class: CompressUtil
Class-Path: D:/my/lib/tar.jar D:/my/lib/activation.jar

but doesn't work. any idea? (I don't want to include those jar)

I read somewhere in google, need to use class loader, anyone can show me how?

thanks

A ClassPath in a jar file manifest must be relative to the jar file itself, not to the local file system. The convention is to simply list the jar file name without a path and plan to keep it in the same directory as the jar file you're creating.

So, you'd want to change your entry to:

Class-Path: tar.jar activation.jar

Another quirk of manifests in jar files is that you must have an extra line feed character at the end of the file.
 
Don't get me started about those stupid light bulbs.
