In my setup the jars are all listed in the manifest but they don't have any directory prepended. The jar with main is in the same directory as the jars listed in its manifest. The script that runs it cds to that directory. It doesn't set classpath since the current directory is normally in it.
If I understand your description, with your setup the jars in the manifest would each need to have the lib directory prepended to them (classpathPrefix). The advantage of my method (probably minor) is that I can move the work and lib directories (since they are the same directory) and it still works. The disadvantage is that each app has its own copy of the jar files, but that could be an advantage since I don't have to worry about version issues with shared jars.
