video in jar

I have been trying to make a full screen video application following the instructions on
http://processing.org/discourse/yabb/board_Tools_action_display__num_1074127030_start_15.html
I include the BVideo.class, BVideo$Handler.class and the comm.jar in my mirrorCam2.jar
I have made a batch file containing:
start javaw -cp mirrorCam2.jar mirrorCam2
but when I start it, I get the following error:
"Fatal exception occured. Program will exit."
Do you know how I can get this to work - here is my code:
// mirrorCam2
// by lars <http://www.larsjessen.dk>
// Compares the frame captures from the camera to a reference image. For a new reference image press the mouse
// Created 15 Sep 2004
// full-screen main function edit by Tom Carden
// originally provided by michael05
static public void main(String args[]) {
try {
Frame frame = new Frame();
// !!!
// change this to your sketch name...
Class c = Class.forName("mirrorCam2");
BApplet applet = (BApplet) c.newInstance();
applet.init();
applet.start();
// get default screendevice and configuration
GraphicsDevice gd = GraphicsEnvironment.getLocalGraphicsEnvironment().getDefaultScreenDevice ();
GraphicsConfiguration gc = gd.getDefaultConfiguration();
frame.setUndecorated(true);
frame.setBackground(Color.black);
frame.setLayout(new GridBagLayout());
frame.add(applet);
frame.pack();
// test if fullscreen mode is available (jvm 1.4+) and activate it
if (gd.isFullScreenSupported()) {
gd.setFullScreenWindow(frame);
}
// test if display mode is available (jvm 1.4+) and set it to the
// size of the applet
if (gd.isDisplayChangeSupported()) {
gd.setDisplayMode(new DisplayMode(applet.g.width, applet.g.height, 32, 0));
}
frame.setLocation(0, 0);
frame.show();
applet.requestFocus();
frame.addWindowListener(new WindowAdapter() {
public void windowClosing(WindowEvent e) {
System.exit(0);
}
});
} catch (Exception e) {
e.printStackTrace();
System.exit(1);
}
}
//end of full screen code
int xpos = 0;
int ypos = 0;
int captureWidth = 640;
int captureHeight = 480;
color[] pixelArray;

int motionCounter = 0;
void setup()

framerate(20);

set(ii,i, video.pixels[index]);//c = color(255,255,255);
} else {
set(ii,i, color(0,0,0) );
}
index++;
}
}
//println("motion: " + motionCounter);
motionCounter = 0;
newFrame = false;
}
}
