KeyListener bug

Because of some odd reason, my key listener doesn't work. If you can help me that would be great.
Here is my eclipse workspace: Pong_WORKSPACE.zip
and here are all the class files on their own.

Pong.java (main class)

Code :

package net.nivangerow.pong;
import javax.swing.*;
import java.awt.*;
public class Pong {
	public static void main(String[] args)
	{
		JFrame frame = new JFrame("Pong by nivangerow");
		frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		frame.setVisible(true);
		frame.setSize(640, 480);
		frame.add(new Game());
	}
}

Game.java

Code :

package net.nivangerow.pong;
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class Game extends JPanel implements ActionListener{
	Timer time;
	Image ball;
	public Bat b3;
	public Game()
	{
		b3=new Bat();
		setVisible(true);
		setSize(640, 480);
		setBackground(Color.BLACK);
		time = new Timer(5, this);
		time.start();
		ImageIcon b2 = new ImageIcon(getClass().getResource("ball.png"));
		ball = b2.getImage();
		addKeyListener(new AL());
	}
	public void actionPerformed(ActionEvent e)
	{
		//System.out.println(b3.y+" "+b3.py);
		b3.move();
		repaint();
	}
	public void paint(Graphics g)
	{
		super.paint(g);
		Graphics2D g2d = (Graphics2D)g;
		g2d.drawImage(b3.bat, 0, b3.y, null);
	}
	public class AL extends KeyAdapter
	{
		public void keyPressed(KeyEvent e)
		{
			int key = e.getKeyCode();
			if(key==KeyEvent.VK_W)
			{
				b3.py=-1;
			}
		}
		public void keyReleased(KeyEvent e)
		{
			int key = e.getKeyCode();
			if(key==KeyEvent.VK_W)
			{
				b3.py=0;
			}
		}
	}
}

Bat.java

Code :

package net.nivangerow.pong;
import java.awt.*;
import javax.swing.ImageIcon;
public class Bat {
	public int y=180;
	public int py=0;
	Image bat;
	public Bat()
	{
		ImageIcon b1 = new ImageIcon(getClass().getResource("bat.png"));
		bat = b1.getImage();
	}
	public void move()
	{
		//System.out.println("MOVING");
		y = y + py;
	}
}
