This HTML can be used to launch the applet: 
<object code="MyApplet" width=240 height=100> 
public class MyApplet extends JApplet { 
  JButton jbtnOne; 
  JButton jbtnTwo; 
  JLabel jlab; 
  public void init() { 
    try { 
      SwingUtilities.invokeAndWait(new Runnable () { 
        public void run() { 
          guiInit(); // initialize the GUI 
    } catch(Exception exc) { 
      System.out.println("Can't create because of "+ exc); 
  // Called second, after init().  Also called 
  // whenever the applet is restarted.  
  public void start() { 
    // Not used by this applet. 
  // Called when the applet is stopped. 
  public void stop() { 
    // Not used by this applet. 
  // Called when applet is terminated.  This is 
  // the last method executed. 
  public void destroy() { 
    // Not used by this applet. 
  // Setup and initialize the GUI.  
  private void guiInit() { 
    // Set the applet to use flow layout. 
    setLayout(new FlowLayout()); 
    // Create two buttons and a label. 
    jbtnOne = new JButton("One"); 
    jbtnTwo = new JButton("Two"); 
    jlab = new JLabel("Press a button."); 
    // Add action listeners for the buttons. 
    jbtnOne.addActionListener(new ActionListener() {      
      public void actionPerformed(ActionEvent le) {  
        jlab.setText("Button One pressed.");  
    jbtnTwo.addActionListener(new ActionListener() {      
      public void actionPerformed(ActionEvent le) {  
        jlab.setText("Button Two pressed.");  
    // Add the components to the applet's content pane.
