Here would be the steps to follow:
1. select a .class file, call lister (F3)
2. jad the .class file
3. show in lister
I'm able to do this with class files that resides on regular filesystem, using an user action with a bat file, but the main goal would be to use the magical F3 key when navigating inside Java Archive (jar, ear, war files).
Unfortunately I'm a pure java dev ... and that would annoy me to re-learn C programming to write this kind of lister ...
