Did you download the jars using Firefox?  I had this issue where downloading the jars direclty ended up wrapping
the jars in an extra layer of zip file, ie. my jogl-all.jar ended up having only one file in the archive...called jogl-all.jar

Pulling out that file and using it directly solved it for me. (still no idea how that happened)
