Trouble with Simple Game


I think I have the jME2 and jME2Physics code compiled properly and added as librarys to a new test application. I'm trying to get a simple game instance up and running but I am getting the following error:

I'm not sure, but it seems to be looking for a class from the Light Weight Java Graphics Library, is that included in the jME2 source or should I be looking to obtain that separately?

Also, this is the code I am attempting to run if it helps:

package javaapplication6;

import com.jme.scene.shape.Box;
import com.jme.math.Vector3f;

public class Main extends SimpleGame
   public static void main(String[] args)
      Main app = new Main();

    protected void simpleInitGame()
        // Make a box
        Box b = new Box("Mybox", new Vector3f(0,0,0), new Vector3f(1,1,1));
        rootNode.attachChild(b); // Put it in the scene graph


You can find it in the /lib/lwjgl folder of your jME checkout. Also be sure to add the lwjgl native found in lib/lwjgl/native to your library path.
