pkunzip problem

[Dave Plauger - HPC Engineering]

When I edit a jar file, e.g.: /jdk1.2.2/src.jar, and try to find a file
('f' command) this happens:

    'pkunzip' exited with status 9

I've download a few versions of pkunzip (from pk204g.exe) with no
success.

winzip extracts from the jar file ok, but it would be nice if emacs JDE
could do it too.

Any ideas?
