  public class JInternalFrame1 extends JFrame implements ActionListener{
      
      JDesktopPane desktopPane;
      int count = 1;
      
      public JInternalFrame1() {
          super("JInternalFrame1");
          Container contentPane = this.getContentPane();
          contentPane.setLayout(new BorderLayout());
          
          JButton b = new JButton("Create New Internal Frames");
          b.addActionListener(this);//当用户按下按钮时，将运行actionPerformed()中的程序
          contentPane.add(b, BorderLayout.SOUTH);
          /*建立一个新的JDesktopPane并加入于contentPane中
           */
          desktopPane = new JDesktopPane(); 
          contentPane.add(desktopPane); 
  
          setSize(350, 350); 
          show(); 
          
          addWindowListener(new WindowAdapter() {
              public void windowClosing(WindowEvent e) {
                      System.exit(0);
              }
          });
      }
      /*产生一个可关闭、可改变大小、具有标题、可最大化与最小化的Internal Frame.
       */
      public void actionPerformed(ActionEvent e)
      {
          JInternalFrame internalFrame = new JInternalFrame(
          "Internal Frame "+(count++), true, true, true, true);  
  
          internalFrame.setLocation( 20,20);
          internalFrame.setSize(200,200); 
          internalFrame.setVisible(true);
          //取得JInternalFrame的Content Pane,用以加入新的组件。
          Container icontentPane = internalFrame.getContentPane();
          JTextArea textArea = new JTextArea();
          JButton b = new JButton("Internal Frame Button");
          /*将JTextArea与JButton对象加入JInternalFrame中。由此呆知，JInteranlFrame加入组件
           *的方式与JFrame是一模一样。
           */
          icontentPane.add(textArea,"Center");
          icontentPane.add(b,"South");
          //将JInternalFrame加入JDesktopPane中，如此一来，即使产生很多JInternalFrame,JDesktopPane也
          //能将它们之间的关系管理得相当良好。
          desktopPane.add(internalFrame);  
          
          try {
              internalFrame.setSelected(true);
          } catch (java.beans.PropertyVetoException ex) {
            System.out.println("Exception while selecting");
          }
      }
  
      public static void main(String[] args) {
          new JInternalFrame1();
      }
  }
  
  

------ Solution --------------------- -----------------------
J2EE where you can create a child window of the JSP page , the parent page to write a JS function that is called when the jump

var returnValue = window.showModalDialog ("operate.do? operate = ....");
------ Solution ------------ --------------------------------

  import java.awt.*;
  import java.awt.event.*;
  import javax.swing.*;
  
  public class FrameTest extends JFrame 
  {
  	private JButton btn = new JButton("打开子窗口");
  	
  	public FrameTest()
  	{
  		setTitle("主窗口");
  		setSize(400, 300);
  		setLayout(new FlowLayout());
  		add(btn);
  		btn.addActionListener(new ActionListener()
  			{
  				public void actionPerformed(ActionEvent event)
  				{
  					new SubFrame();
  				}
  			});
  		setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
  		setLocationByPlatform(true);
  		setVisible(true);
  	}
  	
  	public static void main(String[] args)
  	{
  		new FrameTest();
  	}
  }
  
  class SubFrame extends JFrame
  {
  	public SubFrame()
  	{
  		setTitle("子窗口");
  		setSize(400, 300);
  		setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);

  		setVisible(true);
