Im using netbeans, also opengl.jar and jogl.jar are imported ...


whats wrong??

package dimenciontest;
import processing.core.*;
import processing.opengl.*;

public class Main extends PApplet {

   public Main() {
   }

   public static void main(String[] args) {

  PApplet.main( new String[]{"dimenciontest.Main"} );
   }

  float a;

   @Override
 public  void setup() {
   size(640, 480, OPENGL); // Change size to 320 x 240 if too slow at 640 x 480



}
 
  @Override
public void draw() {

  }


and i get the following error :
