[JToolTip]

I don't see whats wrong with this code. It looks fine, but the applet on the website doesn't show the gui at all

Code:

import java.applet.*;
import java.awt.*;
import java.awt.event.*;
import java.io.*;
import java.net.*;
import javax.swing.*;
public class Client extends JApplet implements ActionListener
{
   public void init()
   {
      setContentPane(new Client());
   }
   public static JMenuBar menuBar = new JMenuBar();
   public static JMenu file = new JMenu("File");
   public static JMenuItem home = new JMenuItem("Main Page");
   public static JPanel panel = new JPanel(new BorderLayout());
   public static JLabel intro = new JLabel("Welcome.");
   public Client() {
   	setLayout(new BorderLayout());
   	setJMenuBar(menuBar);
   			menuBar.add(file);
   					file.add(home);
   							home.addActionListener(this);
	setLayout(new BoxLayout(panel, BoxLayout.PAGE_AXIS));
   	panel.add(intro);
   }
   public void actionPerformed(ActionEvent e) {
   	Object s = e.getSource();
   	if(s == home) {
	intro.setText("Once again, welcome!");
   	}
   }
}
