Problem with KeyListener

Hello!
I have tried to get a JPanel implement the KeyListener interface but I can't get it to work. It does not indicate any keystrokes at all.
Below is the full code and my opinion is that I would get different output when I press, type or release a key. But nothing happens.

Any suggestions are welcome.

Best regards
Fredrik

import javax.swing.*;
import java.awt.*;
import java.awt.event.*;

public class Main extends JFrame
{
    MyPanel myPanel = new MyPanel();

    public Main()
    {
        super("KeyListener Tester");
        setSize(300, 300);
        getContentPane().add(myPanel);
        show();
    }

    public static void main(String[] args)
    {
        new Main();
    }
}

class MyPanel extends JPanel implements KeyListener
{
    public MyPanel()
    {
        setBackground(Color.red);
        addKeyListener(this);
        requestFocus();
    }

    public void keyPressed(KeyEvent ke)
    {
        System.out.println("keyPressed");
    }

    public void keyReleased(KeyEvent ke)
    {
        System.out.println("keyReleased");
    }

    public void keyTyped(KeyEvent ke)
    {
        System.out.println("keyTyped");
    }
}
