How to capture remote control events

Question

Hello, I am now writing some simple xlets to test UI .
I can successfully receive arrow key and enter using KeyEvent,but failed at color key and other
keys in remote control. I have read some articles and got quite confused about the event model
of MHP,it seems complex to beginners.
I tried to receive color key event by this way:
a: main class (HComponent) implements xlet and UserEventListener;
b: define one userEventRepostiroy colorKey and add all colored key to it.
c: EventManager.getInstance().addUserEventListener(this,colorKey);
d:implement the userEventReceived method
I tried the color keys in remote control of my emulator ,but not captured, Can you tell me why? Thanks!!!!

Hi,
I am trying to program a normal JFrame application which can capture remote control inputs. (I know very little about Xlets. I just need a listener for an application).
Many of the buttons are captured by a normal KeyListener but some aren't (player controls like play/pause and red/green/yellow/blue colour buttons). Also, most of the ones that are captured just have keyCode() = 0 and keyChar() = '' so I can't determine which button was actually pressed.
Is there any way I can implement the UserEventListener example above without using an Xlet? Alternatively, is there any way I can manipulate KeyListener to get ALL button presses from the remote control? Any other ideas?
Thanks,
Brian
PS - here is my attempt: (Am I missing the point altogether? Not sure if a UserEventListener can be added to a component like other listeners)
package remotecontrol;
import javax.swing.JFrame;
import org.dvb.event.*;
public class frame extends JFrame implements UserEventListener
    public frame()
        UserEventRepository rep = new UserEventRepository("whatever");
        rep.addAllArrowKeys();
        rep.addAllNumericKeys();
        rep.addAllColourKeys();
        EventManager.getInstance().addUserEventListener(this, rep);
        setSize(200,100);
        setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
        show();
    public static void main(String[] args)
        frame app = new frame();
    public void userEventReceived(UserEvent userEvent)
        System.out.println("Remote button press captured: " + userEvent.getCode());
}
