I'm trying to run this code in Eclipse:

http://jogamp.org/wiki/index.php/JOCL_Tutorial

I've set up my class path like this:

when I run the code I get:

Catched ZipException: error in opening zip file, while addNativeJarLibsImpl(classFromJavaJar class com.jogamp.common.os.Platform, classJarURI jar:file:/Users/nyholku/JoclTests/jogamp-all-platforms-v2.1.1/jar/gluegen.jar!/com/jogamp/common/os/Platform.class, nativeJarBaseName gluegen-natives-macosx-universal.jar): [ file:/Users/nyholku/JoclTests/jogamp-all-platforms-v2.1.1/jar/gluegen.jar -> file:/Users/nyholku/JoclTests/jogamp-all-platforms-v2.1.1/jar/ ] + gluegen-natives-macosx-universal.jar -> slim: jar:file:/Users/nyholku/JoclTests/jogamp-all-platforms-v2.1.1/jar/gluegen-natives-macosx-universal.jar!/

and I can't figure out what I'm doing wrong.

An almost identical project/build path setup in Eclipse works for me with jogl.
