Help! Can't display!

Question

It seems like there's a ton of information about the conceptual structure of Java TV on the internet, and great documentation for all the functions, but there's no intermediary material that discusses which classes/functions relate to which concepts. For example, there's no direct mapping between an object structure and the three-layer model, at least as far as I know. As a result, I've been trying for days to get a simple Xlet working that simply displays a white screen, with no luck.
Here's the code that I'm working on. Basically, when it runs I want it to create a white screen, but it instead does absolutely nothing. I have a feeling that I'm missing a graphics handler or that I am grabbing the wrong container, but I can't seem to locate any source that tells me how to do either correctly.
import java.awt.Color;
import java.awt.Container;
import javax.tv.xlet.Xlet;
import javax.tv.xlet.XletContext;
import javax.tv.xlet.XletStateChangeException;
import org.havi.ui.HGraphicsDevice;
import org.havi.ui.HScene;
import org.havi.ui.HSceneFactory;
import org.havi.ui.HScreen;
public class XletEASMain implements Xlet
     final public static boolean STARTED = true, PAUSED = false;
     private HScene hScene;
     private XletContext context;
     private boolean state;
     public XletEASMain()
     public void initXlet(XletContext context)
         throws XletStateChangeException
          this.context = context;
          this.state = PAUSED;
               HGraphicsDevice device = HScreen.getDefaultHScreen().getDefaultHGraphicsDevice();
               HSceneFactory factory = HSceneFactory.getInstance();
               this.hScene = factory.getFullScreenScene( device );
               if ( this.hScene == null )
                    this.hScene = factory.getDefaultHScene();
               this.hScene.setBackground( Color.white );
               this.hScene.setForeground( Color.white );
     public void startXlet()
          throws XletStateChangeException
          this.state = STARTED;
          this.hScene.validate();
          this.hScene.setVisible( true );
          this.hScene.show();
          this.hScene.repaint(); // just trying stuff at this point; nothing works
     public void pauseXlet()
          this.state = PAUSED;
          this.hScene.setVisible( false );
     public void destroyXlet(boolean unconditional)
          throws XletStateChangeException
          if( unconditional )
               return;
          else
               throw new XletStateChangeException();
}

Answer 1

try to set the hscene bounds. if you are not setting the bounds then hScene should take the default bound of video frame which should be provided by the middleware u use . if in any case your hscene bounce is not set then you cant view your Xlet.
