Was it helpful?

Solution

When you download the JARs directly, some web browsers might wrap it into a ZIP file for "security" reasons. Rather download the 7z archive here and take the JARs it contains. You should follow these detailed instructions, it should work in Eclipse.

I remind you that the separated native libraries are no longer required in JOGL 2, rather use the JARs containing the native libraries, it is a lot less error prone, just put them into the same directory than the Java libraries relying on them (jogl-all.jar and gluegen-rt.jar).
