一个登陆窗口的java程序，如何嵌入到HTML中。实现网页中的登陆
程序是这样的：
------------------------
//====登陆窗口======

import   java.awt.*;
import   javax.swing.*;
import   java.awt.event.*;
public   class   LoginDialogDemo   extends   JFrame{
JButton   button=   new   JButton( "Click   Me ");
JPanel   panel   =   new   JPanel(new   FlowLayout());
public     LoginDialogDemo(){
final   JFrame   frame=   this;
this.getContentPane().add(panel,BorderLayout.SOUTH);
panel.add(button);
button.addActionListener(new   ActionListener(){
public   void   actionPerformed   (ActionEvent   e){
showLoginDialog(frame);
}
});
this.setSize(300,   200);
this.setTitle( "显示登陆对话框 ");
this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
this.show();
}
void   showLoginDialog(JFrame   frame){
JPanel   p   =   new   JPanel   (new   GridLayout(0,1));
JTextField   tfUserName   =   new   JTextField();
JPasswordField   tfPassword   =   new   JPasswordField();
p.add(new   JLabel   ( "Username: "));
p.add(tfUserName);
p.add(new   JLabel   ( "Password: "));
p.add(tfPassword);
if   (JOptionPane.showConfirmDialog(frame,
p,
"Login ",
JOptionPane.OK_CANCEL_OPTION,
JOptionPane.PLAIN_MESSAGE)
==   JOptionPane.OK_OPTION){
System.out.println( "User   Name: "+tfUserName.getText());
System.out.println( "Password: "+   new   String   (tfPassword.getPassword()));
}
}
public   static   void   main(String[]   args){
LoginDialogDemo   frame   =   new   LoginDialogDemo();  
}
}
-----------------------------------------
请问，如何让这个程序在一个WEB页面中，单击登陆后实现登陆呢？这个不是APPLET，我不知道改怎么弄。

------解决方案--------------------
改成 applet ，继承 Applet,重写 几个方法
