HI  my names Richie and i'm 13. I'm writeing this application for my dad
that when you press a button it transferes you to the site. I'm using
Jbuilder 2. This is the code.

package Project;

import java.applet.*;
import java.awt.*;
import java.awt.event.*;
import java.net.*;
import java.lang.*;
import borland.jbcl.control.*;
import borland.jbcl.layout.*;

public class Frame1 extends DecoratedFrame {

  file://Construct the frame
  MenuBar menuBar1 = new MenuBar();
  Menu menuFile = new Menu();
  MenuItem menuFileExit = new MenuItem();
  MenuItem menuFileZD = new MenuItem();
  MenuItem Yahoo = new MenuItem();
  MenuItem menuItem1 = new MenuItem();
  CheckboxPanel checkboxPanel1 = new CheckboxPanel();
  FlowLayout flowLayout1 = new FlowLayout();
  TextArea opinion = new TextArea();
  BevelPanel bevelPanel1 = new BevelPanel();
  Button No = new Button();
  Button Yes = new Button();
  FlowLayout flowLayout2 = new FlowLayout();

  public Frame1() {
    try  {
      jbInit();
    }
    catch (Exception e) {
      e.printStackTrace();
    }
  }
file://Component initialization

  private void jbInit() throws Exception  {
    this.setLayout(flowLayout1);
    this.setSize(new Dimension(475, 450));
    this.setTitle("Frame");
    menuFile.setLabel("File");
    menuFileExit.setLabel("Exit");
    menuFileZD.setFont(new Font("Dialog", 0, 12));
    menuFileZD.setLabel("ZD Net");
    menuFileZD.addActionListener(new java.awt.event.ActionListener() {
      public void actionPerformed(ActionEvent e) {
        menuFileZD_actionPerformed(e);
      }
    });
    Yahoo.setLabel("Yahoo");
    menuItem1.setEnabled(false);
    checkboxPanel1.setGrouped(true);
    checkboxPanel1.setLabels(new String[] {"Yahoo", "ZD Net", "None"});
    checkboxPanel1.setSelectedLabels(new String[] {"None"});
    checkboxPanel1.setSelectedLabel("");
    checkboxPanel1.setTextureName("");
    opinion.setBackground(Color.white);
    opinion.setText("What is your opinion of this Java applet");
    bevelPanel1.setOpaque(false);
    bevelPanel1.setVisible(false);
    No.setLabel("button1");
    Yes.setLabel("button2");
    bevelPanel1.setLayout(flowLayout2);
    opinion.addKeyListener(new java.awt.event.KeyAdapter() {
      public void keyPressed(KeyEvent e) {
        opinion_keyPressed(e);
      }
    });
    menuItem1.setLabel("New Link");

    menuFileExit.addActionListener(new ActionListener()  {
      public void actionPerformed(ActionEvent e) {
        fileExit_actionPerformed(e);
      }
    });


    this.setBackground(SystemColor.info);
    menuFile.add(menuItem1);
    menuFile.add(Yahoo);
    menuFile.add(menuFileZD);
    menuFile.addSeparator();
    menuFile.add(menuFileExit);
    menuBar1.add(menuFile);
    this.add(checkboxPanel1, BorderLayout.CENTER);
    this.add(opinion, null);
    this.add(bevelPanel1, null);
    bevelPanel1.add(Yes, null);
    bevelPanel1.add(No, null);
    this.setMenuBar(menuBar1);
  }
file://File | Exit action performed

  public void fileExit_actionPerformed(ActionEvent e) {
    System.exit(0);
  }

  public void menuFileZD_actionPerformed(ActionEvent evt) {
    URL url = null;
  try {
    url = new URL("http://www.mp3corner.net/hitmix.shtml");
  }
  catch (MalformedURLException a) {
    System.out.println("Bad url :" + url);
  }

}
}

The end bit is what I think needs something to chage to the page. I tried to
put in this but it wouldn't allow it,
getAppletContext().showDocument(url);
