One question about how to use JFrame

Question

Hello friends,
I use a JFrame to show one webpage, I want to follow a link in this page by a new window, but when I used it, I find, each time I create a new window to follow a link, the old window will be nothing, what should I do?
Thanks in advance!
See the following codes:
import javax.swing.text.*;
import javax.swing.*;
import java.net.*;
import java.io.*;
import java.awt.*;
public class SimpleWebBrowser {
public static void main(String[] args) {
// get the first URL
String initialPage = "http://www.yahoo.com";
if (args.length > 0) initialPage = args[0];
// set up the editor pane
JEditorPane jep = new JEditorPane();
jep.setEditable(false);
jep.addHyperlinkListener(new LinkFollower(jep));
try {
jep.setPage(initialPage);
catch (IOException e) {
System.err.println("Usage: java SimpleWebBrowser url");
System.err.println(e);
System.exit(-1);
// set up the window
JScrollPane scrollPane = new JScrollPane(jep);
JFrame f = new JFrame("Simple Web Browser");
f.setDefaultCloseOperation(WindowConstants.DISPOSE_ON_CLOSE);
f.getContentPane().add(scrollPane);
f.setSize(512, 342);
f.show();
import javax.swing.*;
import javax.swing.event.*;
public class LinkFollower implements HyperlinkListener {
private JEditorPane pane;
private JScrollPane window;
public LinkFollower(JEditorPane pane) {      
this.pane = pane;
public void hyperlinkUpdate(HyperlinkEvent evt) {
if (evt.getEventType() == HyperlinkEvent.EventType.ACTIVATED) {
try {
     pane.setPage(evt.getURL());
     window = new JScrollPane(pane);
     JFrame.setDefaultLookAndFeelDecorated(true);
JFrame t = new JFrame();
t.getContentPane().add(window);
     t.setDefaultCloseOperation(WindowConstants.DISPOSE_ON_CLOSE);
t.setSize(800, 600);
t.show();
catch (Exception e) {       

Answer 1

the old window will be nothingBecause you abandon the old frame.
Use it forever.
Beware: Java HTML rendering framework is almost endlessly incomplete. You shouldnIt implement real browser with them.
