Well you know,
If the code looks like:
 public static void main(String[] args) {
        GraphicsConfiguration config =
                SimpleUniverse.getPreferredConfiguration();
    }
we will need more than
jogamp-fat.jar (right?)
In fact;
 final GraphicsEnvironment
                localGraphicsEnvironment
                = getLocalGraphicsEnvironment();
        final GraphicsDevice
                defaultScreenDevice
                = localGraphicsEnvironment.getDefaultScreenDevice();
        GraphicsConfiguration c[] = defaultScreenDevice
                .getConfigurations();
        for (int i = 0; i < c.length; i++) {
            System.out.println("gc:" + i + ":" + c[i]);
        }
        GraphicsConfiguration gc  = c[0];
        Canvas3D c3d = new Canvas3D(gc);
        System.out.println("done");
needs more than jogamp-fat.jar
Don't you need
vecmath.jar j3dutils.jar j3dcore.jar, at the very least?
If I have the correct versions of these things, what I get appears below.
Thanks!

An inability to construct a Canvas3D is a bit of a show stopper, isn't it?
Thanks!
