JOGL supports jogamp.gluegen.UseTempJarCache, it allows to load the native libraries from JARs without having to set the library path, it is very convenient, it eliminates some settings that may be problematic for beginners. I wanted to add this support to JOAL by myself but I don't feel comfortable enough with it to do so.
fixed.
Thank you so much. I'm going to give it a try in several hours.
