I don't know what to do anymore! Background Image is not displayed???!!!

Question

Hey there!
I'm just trying to show a simple jpg in the Background Layer and it does not seem to work! I really need this for my diploma and i do not know where i made the mistake and it is compiling without errors!! Yet the picture is not shown.. Could somebody help me please? Any answer would be very helpful for me for i don't know what to do anymore..I am testing my Xlets with XletView 3.6..
Here is the code i tried:
public class BackgroundImage extends HComponent implements Xlet, Runnable{
private HScene scene;
private Image image;
private HaviBackgroundController backgroundManager;
private XletContext context;
private Thread myWorkerThread;
     public BackgroundImage()
public void initXlet(XletContext context) throws
javax.tv.xlet.XletStateChangeException
          this.context = context;
public void startXlet() throws javax.tv.xlet.XletStateChangeException
     myWorkerThread = new Thread(this);
          myWorkerThread.start();
public void pauseXlet()
          pause();
public void destroyXlet(boolean unconditional) throws javax.tv.xlet.XletStateChangeException
          if (unconditional) {
               destroy();
public void run()
          getResources();
          showBackgroundImage();
public void getResources() {
HSceneFactory factory = HSceneFactory.getInstance();
HSceneTemplate hst = new HSceneTemplate();
hst.setPreference(
HSceneTemplate.SCENE_SCREEN_DIMENSION,
               new org.havi.ui.HScreenDimension(1,1),
               HSceneTemplate.REQUIRED);
          hst.setPreference(
HSceneTemplate.SCENE_SCREEN_LOCATION,
               new org.havi.ui.HScreenPoint(0,0),
               HSceneTemplate.REQUIRED);
scene = factory.getBestScene(hst);
Rectangle rect = scene.getBounds();
setBounds(rect);
setVisible(true);
setBackground(Color.black);
scene.add(this);
scene.setVisible(true);
this.requestFocus();
public void showBackgroundImage() {
MediaTracker tracker = new MediaTracker(this);
image = Toolkit.getDefaultToolkit().getImage("background.jpg");
tracker.addImage(image, 0);
try{
               tracker.waitForAll();
          catch(InterruptedException e) {
               image = null;
          backgroundManager = new HaviBackgroundController();
          if (backgroundManager.init()) {
     backgroundManager.display("background.jpg");
public void pause()
scene.setVisible(false);
     backgroundManager.dispose();
public void destroy()
scene.setVisible(false);
scene.remove(this);
image.flush();
image = null;
backgroundManager.dispose();
HSceneFactory.getInstance().dispose(scene);
scene = null;
}

Sorry, i forgot about that..
I tried the HaviBackgroundController Class of Steve Morris (thanks a lot for that great Tutorial!). It is as follows:
class HaviBackgroundController implements ResourceClient{
private HBackgroundDevice backdevice;
private HStillImageBackgroundConfiguration backconfig;
public boolean init()
HScreen screen = HScreen.getDefaultHScreen();
HBackgroundDevice backdevice = screen.getDefaultHBackgroundDevice();
HBackgroundConfigTemplate backgroundConfigurationTemplate = new
          HBackgroundConfigTemplate();
backgroundConfigurationTemplate.setPreference(
HBackgroundConfigTemplate.FLICKER_FILTERING,
               HBackgroundConfigTemplate.REQUIRED);
          HBackgroundConfiguration backconfig;
          backconfig = backdevice.getBestConfiguration(
               backgroundConfigurationTemplate);
          if (backdevice.reserveDevice(this))
               try
                    backdevice.setBackgroundConfiguration(backconfig);
               catch (Exception ex)
                    System.out.println("Can't initialise the background device");
                    backdevice.releaseDevice();
                    return false;
               if(backconfig instanceof HStillImageBackgroundConfiguration)
                    this.backconfig = (HStillImageBackgroundConfiguration)backconfig;
                    this.backdevice = backdevice;
                    return true;
               else
                    backdevice.releaseDevice();
          return false;
     public void dispose()
          if (backdevice != null)
               backdevice.releaseDevice();
               backdevice = null;
               backconfig = null;
     public void display(String filename)
          if(backconfig != null) {
               HBackgroundImage backimage = new HBackgroundImage("background.jpg");
               try {
                    backconfig.displayImage(backimage);
               catch (java.io.IOException ioe) {
                    System.out.println("Can't display background image - IO exception");
                    ioe.printStackTrace();
               catch (HPermissionDeniedException hpde) {
                    System.out.println("Can't display background image - permission denied");
               catch (HConfigurationException hce) {
                    System.out.println("Can't display background image - configuration exception");
                    hce.printStackTrace();
     public boolean requestRelease(ResourceProxy proxy, Object requestData) {
          return false;
     public void release(ResourceProxy proxy) {
          backdevice.releaseDevice();
     public void notifyRelease(ResourceProxy proxy) {
          backdevice.releaseDevice();
}
