Hi

JOGL 2.0 is necessary to run Java3D. You need jogl.all.jar, gluegen-rt.jar and all JARs containing the native libraries for the platform(s) you wish to support. Just download them here this time:

The JARs containing the native libraries don't have to be in the classpath but they have to be in the same directory that jogl.all.jar and gluegen-rt.jar. Put jogl.all.jar and gluegen-rt.jar into your classpath too. Maybe look at this for Netbeans IDE:
