So I'm trying to make a simple jogl applet and I've been able to get my project to run in Eclipse but I can not get it to work online. I've been here  http://jogamp.org/jogl-demos/www/applettest-jnlp.html and tried to do this but I just get a blank region where my applet should be.

This is what I'm using for my class. I exported the class to a jar using the standard eclipse export.

import java.applet.Applet;

import javax.media.opengl.GL;
import javax.media.opengl.GL2;
import javax.media.opengl.GLAutoDrawable;
import javax.media.opengl.GLCapabilities;
import javax.media.opengl.GLEventListener;
import javax.media.opengl.GLProfile;
import javax.media.opengl.awt.GLCanvas;

import com.jogamp.opengl.util.Animator;
import com.jogamp.opengl.util.FPSAnimator;

public class AppletLauncherJogl extends Applet implements GLEventListener {

        /**
         *
         */
        private static final long serialVersionUID = -5349107458641586294L;

    public void init() {
        GLProfile glp = GLProfile.getDefault();
        GLCapabilities caps = new GLCapabilities(glp);
        GLCanvas canvas = new GLCanvas(caps);
       
        canvas.setSize(400, 400);
        canvas.setVisible(true);
        add(canvas);
       
        canvas.addGLEventListener(new AppletLauncherJogl());
       
        this.start();

        Animator animator = new FPSAnimator(canvas, 60);
        animator.add(canvas);
        animator.start();
    }

    @Override
    public void display(GLAutoDrawable drawable) {
        update();
        render(drawable);
    }

    @Override
    public void dispose(GLAutoDrawable drawable) {
    }

    @Override
    public void init(GLAutoDrawable drawable) {
    }

    @Override
    public void reshape(GLAutoDrawable drawable, int x, int y, int w, int h) {
    }

    private void update() {

    }

    private void render(GLAutoDrawable drawable) {
        GL2 gl = drawable.getGL().getGL2();

        gl.glClear(GL.GL_COLOR_BUFFER_BIT);

        gl.glBegin(GL.GL_TRIANGLES);
                gl.glColor3f(1, 0, 0);
               
                gl.glVertex3d(0, 0, 0);
                gl.glVertex3d(0, 0.5, 0);
                gl.glVertex3d(0.5, 0, 0);
        gl.glEnd();
    }
}

This is my html

<applet code="org.jdesktop.applet.util.JNLPAppletLauncher"
      width=600
      height=400
      archive="http://jogamp.org/deployment/util/applet-launcher.jar,
               http://jogamp.org/deployment/webstart/nativewindow.all.jar,
               http://jogamp.org/deployment/webstart/jogl.all.jar,
               http://jogamp.org/deployment/webstart/gluegen-rt.jar,
               MyURL/AppletLauncherJogl.jar">
   
   
   
   
   
   
   
   
   
</applet>

and this is my jnlp file

<?xml version="1.0" encoding="utf-8"?>
<jnlp href="MyURL/AppletLauncherJogl">

    <title>AppletLauncherJogl</title>

      <jar href="MyURL/AppletLauncherJogl.jar" main="true"/>
      <extension name="jogl-all-awt" href="http://jogamp.org/deployment/webstart/jogl-all-awt.jnlp" />
    </resources>

  <applet-desc
      name="AppletLauncherJogl"
      main-class="AppletLauncherJogl"
      width="640"
      height="480">
  </applet-desc>
</jnlp>

I'm not sure really where the problem is but any help would be really appreciated. I've been stuck for quite and while. Thanks.
