Need some basic help with applets

Question

Hey all, I've never made an applet before and I'm having a small problem. Basically, when I load my applet, the GUI comes up on a separate window (doesn't load within the applet window). Here's my code:
Here's the GUI class.
import java.awt.BorderLayout;
import java.io.File;
import java.util.Vector;
import javax.swing.DefaultComboBoxModel;
import javax.swing.DefaultListModel;
import javax.swing.JButton;
import javax.swing.JFileChooser;
import javax.swing.JList;
import javax.swing.JScrollPane;
import javax.swing.JTextField;
import javax.swing.JTextPane;
import javax.swing.ListModel;
import javax.swing.WindowConstants;
import javax.swing.SwingUtilities;

public class GUI extends javax.swing.JFrame {

}Here's the class my HTML file calls:
import java.applet.Applet;
import javax.swing.JFrame;
public class Main extends Applet{
     //Mainframe
     //JFrame f = new JFrame();
     public void init() {
          GUI inst = new GUI();
          inst.setLocationRelativeTo(null);
          inst.setVisible(true);
          //f.setContentPane(inst.getContentPane());
     public void start() {
        System.out.println("Starting...");
  public void stop() {
        System.out.println("Stopping...");
}

Answer 1

// <applet code='Main' width='400' height='200' ></applet>
import javax.swing.*;
public class Main extends JApplet{
    public void init() {
        GUI inst = new GUI();
        getContentPane().add(inst.getContentPane());
        validate();
    public void start() {
        System.out.println("Starting...");
    public void stop() {
        System.out.println("Stopping...");
}Other notes:
- You try to set the PLAF to Windows. which will not work on Linux and Mac (and if it did, the users would be screaming at you).
- setLayout(null)/setBounds(int,int,int,int) is rubbish GUI development, it is fragile and will cause problems (especially if changing PLAFs)
- Why did you not code this as a hybrid application/app?
- The call to the JFileChooser will require a trusted applet, and it is pointing to the wrong place in seeking out the 'Program Files' directory, better to put configuration data/history data in a sub-dir or user.home.
- This app. is much better suited to being deployed using Java Web Start. Forget the applet and use the frame, persistence can be obtained through the PersistenceService and that will side step both the application needing 'trust' and trying to find a suitable path for storing results of past games. JWS can launch the app. directly off the net, and provides auto-update and many other slick features.
