I have an applet that works fine from the Forte IDE in the applet viewer, but won't work on a web page on local disk:

I don't override the START() method, or any other applet method:

public class ZoneApplet extends javax.swing.JApplet {
    
    ZoneData MyZoneData = new ZoneData();
    
    public ZoneApplet() {
        initComponents();
    }
    
    private void initComponents() {
        jButtonCalc = new javax.swing.JButton();
        jLabel1 = new javax.swing.JLabel();
        jLabel2 = new javax.swing.JLabel();
        jLabel3 = new javax.swing.JLabel();
        jLabel4 = new javax.swing.JLabel();
        jLabel5 = new javax.swing.JLabel();
        jTextFieldOrigin = new javax.swing.JTextField();
        jTextFieldDest = new javax.swing.JTextField();
        jTextFieldRate = new javax.swing.JTextField();
        getContentPane().setLayout(new org.netbeans.lib.awtextra.AbsoluteLayout());
        jButtonCalc.setText("Calculate Rate");
        jButtonCalc.setBorder(new javax.swing.border.BevelBorder(javax.swing.border.BevelBorder.RAISED));
        jButtonCalc.addActionListener(new java.awt.event.ActionListener() {
            public void actionPerformed(java.awt.event.ActionEvent evt) {
                jButtonCalcActionPerformed(evt);
            }
        });
        getContentPane().add(jButtonCalc, new org.netbeans.lib.awtextra.AbsoluteConstraints(140, 90, 110, 30));
        jLabel1.setHorizontalAlignment(javax.swing.SwingConstants.CENTER);
        jLabel1.setText("Origin Zone");
        getContentPane().add(jLabel1, new org.netbeans.lib.awtextra.AbsoluteConstraints(40, 10, -1, -1));
        jLabel2.setHorizontalAlignment(javax.swing.SwingConstants.CENTER);
        jLabel2.setText("Dest. Zone");
        getContentPane().add(jLabel2, new org.netbeans.lib.awtextra.AbsoluteConstraints(160, 10, -1, -1));
        jLabel3.setHorizontalAlignment(javax.swing.SwingConstants.CENTER);
        jLabel3.setText("Rate");
        getContentPane().add(jLabel3, new org.netbeans.lib.awtextra.AbsoluteConstraints(50, 70, 40, -1));
        jLabel4.setHorizontalAlignment(javax.swing.SwingConstants.CENTER);
        jLabel4.setText("Town Car Zone to Zone Calculator");
        getContentPane().add(jLabel4, new org.netbeans.lib.awtextra.AbsoluteConstraints(10, 130, 240, -1));
        jLabel5.setHorizontalAlignment(javax.swing.SwingConstants.CENTER);
        jLabel5.setText("By Steven Schowiak");
        getContentPane().add(jLabel5, new org.netbeans.lib.awtextra.AbsoluteConstraints(70, 150, -1, -1));
        jTextFieldOrigin.setFont(new java.awt.Font("Dialog", 0, 18));
        jTextFieldOrigin.setHorizontalAlignment(javax.swing.JTextField.CENTER);
        jTextFieldOrigin.setBorder(new javax.swing.border.BevelBorder(javax.swing.border.BevelBorder.LOWERED));
        getContentPane().add(jTextFieldOrigin, new org.netbeans.lib.awtextra.AbsoluteConstraints(40, 30, 60, 30));
        jTextFieldDest.setFont(new java.awt.Font("Dialog", 0, 18));
        jTextFieldDest.setHorizontalAlignment(javax.swing.JTextField.CENTER);
        jTextFieldDest.setBorder(new javax.swing.border.BevelBorder(javax.swing.border.BevelBorder.LOWERED));
        getContentPane().add(jTextFieldDest, new org.netbeans.lib.awtextra.AbsoluteConstraints(160, 30, 60, 30));
        jTextFieldRate.setFont(new java.awt.Font("Dialog", 1, 18));
        jTextFieldRate.setHorizontalAlignment(javax.swing.JTextField.CENTER);
        jTextFieldRate.setBorder(new javax.swing.border.BevelBorder(javax.swing.border.BevelBorder.LOWERED));
        getContentPane().add(jTextFieldRate, new org.netbeans.lib.awtextra.AbsoluteConstraints(20, 90, 100, 30));
    }
    private void jButtonCalcActionPerformed(java.awt.event.ActionEvent evt) {
        
        int x,y,rate;
        String strJunk = new String();
        
        strJunk = jTextFieldOrigin.getText();
        try{
            x = Integer.parseInt(strJunk);
        }
        catch(NumberFormatException exc){
            jTextFieldOrigin.setText("");
            return;
        }
        
        if (x > 24 || x < 1){
            jTextFieldOrigin.setText("");
            return;
        }
        
        strJunk = jTextFieldDest.getText();
        try{
            y = Integer.parseInt(strJunk);
        }
        catch(NumberFormatException exc){
            jTextFieldDest.setText("");
            return;
        }
        
        if (y > 24 || y < 1){
            jTextFieldDest.setText("");
            return;
        }
        
        rate = MyZoneData.GetRate(x, y);
        jTextFieldRate.setText("$" + Integer.toString(rate) + ".00");
        
    }

Any clues? I have none!
Thanks.

What browser are you using. I have to use a Java Plug-in to view the applet on the web page.
Did you try it using the Java Plug-IN

At first, it didn't work in either IE or Nutscrape 7.0. I removed the Absolute layout manager and used a null layout manager. NOW, it works fine in Nutscrape, but NOT in IE. In Netscape, the little coffeecup icon appears, telling my the Sun Java VM is running. This doesn't happen with IE. I have Service Pack 1 for XP installed, which has the Microshaft VM
So now what do I do?

ANSWER:
Microschlock's VM blows. Downloaded SUN VM, and installed. Applet works in Internet Enema now.
I got a clue when I installed Nutscrape which uses the Sun VM plugin and it worked.
Thanks all.
