Swing/Applet question

[Chris Stewart]

I'm doing a homework assignment (not due until the 26th) and I've run into a problem with the display. The homework is to code an applet that uses the JOptionPane object showing the user some messages and allowing text input. There is also a number guessing game involved (the project reqs, http://www.isy.vcu.edu/~jmay/hw2). I know how to do everything this project asks, I'm just having an issue with the display.
Just to let you all know, I really only have to use the JOptionPane object to do all of the given tasks, but our professor said if we do extra stuff with the homework we'll get really high grades (i.e., 110 out of 100). So I wanted to create a nice looking swing application containing objects for each aspect of the project (a label for the current amount of money in your account, a label showing the option screens as you encounter them, etc). The problem is I'm not able to view the JPanel code when I view it on my webspace. If I run my program in JBuilder, everything runs and shows up fine. When I run it in IE from my webspace, the login part runs fine but when it should show the panel, submit button, and such it doesn't. Can anyone please look over this and tell me why this happens?
Here is my applet in current form:
http://www.isy.vcu.edu/~cstewart/Hw2Casino.html - btw, the password is casino.
Here is the code:

package vcu.info250.homework2;
import java.awt.*;
import java.awt.event.*;
import java.applet.*;
import javax.swing.*;

public class Hw2Casino extends JApplet
{
  //Password GUI components
  JLabel pwdLabel = new JLabel("Password");
  JPasswordField pwdField = new JPasswordField();
  JButton submitBtn = new JButton("Submit");
  public void init()
  {
    this.loginLogic();
    JPanel p = new JPanel();
    p.setLayout(new GridLayout(2, 2));
    p.add(pwdLabel);
    p.add(pwdField);
    p.add(submitBtn);
    submitBtn.addActionListener(new ActionListener() {
      public void actionPerformed(ActionEvent event) {
        //action
      }
    });
    Container content = getContentPane();
    content.setLayout(new GridBagLayout());
    content.add(p);
  }
  public void loginLogic()
  {
    int i = 3;
    while(i > 0)
    {
      String pwdText = JOptionPane.showInputDialog(null, "Enter your password: ", "Please login", JOptionPane.INFORMATION_MESSAGE);
      if(pwdText.equals("casino"))
      {
        i = 0;
      }
      else
      {
        i--;
        if(i == 0)
        {
          JOptionPane.showMessageDialog(null, "Your chances are up!", "Bye!!!", JOptionPane.ERROR_MESSAGE);
          System.exit(0);
        }
        else
        {
          JOptionPane.showConfirmDialog(null, "Your password was " +
            "incorrect!  You now have " + i + " more attempts.", "Incorrect!", JOptionPane.PLAIN_MESSAGE);
        }
      }
    }
  }
}

Damn, I feel like a moron. When I compiled, it created two class files (Hw2Casino$1.class and Hw2Casino.class). When I uploaded to my webspace, I only uploaded Hw2Casino.class. After uploading the second one, everything works out fine.

Glad we could help

It's usually a good idea to use a JAR file when delivering applets. That way, as long as you JAR'd all the classes, you only have one file to upload to the web server.
Additionally, I would suggest using Java Web Start (JWS) instead of an applet. I realize this was a homework assignment and you were required to use an applet, but JWS apps are much more efficient and they perform better than applets.
Let me know if you would like any additional information.
BTW - I often post questions and realize I made a stupid mistake, luckily before anyone repsponds pointing out my idiotic mistake. So don't be too hard on yourself.

Thanks guys.
I got a good ways into what I wanted to do today, but I ran into an issue. I need help capturing the events from the submit button. I really can't figure out how to handle that. I went ahead and started to code just the bare reqs of my homework (in case I don't get the "fluff" version finished). Could anyone help me understand how I can handle this?
Bare req code:

package vcu.info250.homework2;
import javax.swing.JOptionPane;
import javax.swing.JApplet;
import javax.swing.JButton;
import java.awt.Container;
import java.awt.event.ActionListener;
import java.awt.event.ActionEvent;

public class Hw2Casino extends JApplet
{
  int money = 500;
  public void init()
  {
    Container c = getContentPane();
    JButton button = new JButton("Homework #2");
    button.addActionListener(new ActionListener()
    {
      public void actionPerformed( ActionEvent event )
      {
        hw2();
      }
     }
    );
    c.add(button);
  }
  private void hw2()
  {
    int i = 3;
    while(i > 0)
    {
      String pwdText = JOptionPane.showInputDialog(null, "Enter your password: \n " +
        "~Note~ You have 3 chances", "Please login", JOptionPane.INFORMATION_MESSAGE);
      if(pwdText.equals("casino"))
      {
        while(true)
        {
          String strChoice = JOptionPane.showInputDialog(null, "Please choose a game!\n " +
            " 1. Number Game \n " +
            " 2. Blackjack \n " +
            " 3. Poker \n " +
            " 4. Money Count \n " +
            " 5. Quit \n ", "Please choose a game!", JOptionPane.QUESTION_MESSAGE);
          int choice = Integer.parseInt(strChoice);
          switch(choice)
          {
            case 1:
              JOptionPane.showMessageDialog(null, "The Number Game, code coming soon...");
              break;
            case 2:
              JOptionPane.showMessageDialog(null, "Blackjack is currently under development.  Please try back later.");
              break;
            case 3:
              JOptionPane.showMessageDialog(null, "Poker is currently under development.  Please try back later.");
              break;
            case 4:
              JOptionPane.showMessageDialog(null, "You have $" + money + " in your account");
              break;
            default:
              JOptionPane.showMessageDialog(null, "Thank you for playing!");
              System.exit(0);
              break;
          }
        }
      }
      else
      {
        i--;
        if(i == 0)
        {
          JOptionPane.showMessageDialog(null, "Your chances are up!", "Bye!!!", JOptionPane.ERROR_MESSAGE);
          System.exit(0);
        }
        else
        {
          JOptionPane.showConfirmDialog(null, "Your password was " +
            "incorrect!  You now have " + i + " more attempts.", "Incorrect!", JOptionPane.PLAIN_MESSAGE);
        }
      }
    }
  }
}

Here is how far I got with the "fluff" version.
