Start: Applet not initiallized

Hi,
Sorry if this is in the wrong place, i didnt know whether to post it under applets or under what wrong with my code...
So, i have an applet that im trying to run in the browser with this HTML code:

Code :

<!-- This file automatically generated by BlueJ Java Development  -->

    <body>
        <h1>FindAddApplet Applet</h1>
        <hr>
        <applet code="FindAddApplet.class" 
            width=500 
            height=500
            codebase="/home/pottsie/TutorProgram"
            archive="file:/usr/share/bluej/bluejcore.jar,file:/usr/share/bluej/junit-4.8.2.jar,file:/home/pottsie/TutorProgram/"
            alt="Your browser understands the &lt;APPLET&gt; tag but isn't running the applet, for some reason."
         >
 
            Your browser is ignoring the &lt;APPLET&gt; tag!      
        </applet>
        <hr>
    </body>
</html>

However each time i run it i get the error "Start: Applet not initialized"...

This is the code i am trying to run:

Code :

import java.applet.*;
import java.awt.*;
import java.util.*;
import java.awt.event.*;
import javax.swing.JEditorPane;
import javax.swing.*;
public class FindAddApplet extends Applet implements ActionListener
{ 
    private JLabel jcomp1;
    private JButton nextButton;
    private JButton prevButton;
    private JPanel contentPanel;
    //content layout
    private CardLayout cardLayout;
    //jpanel cards
    ClassYearCard classYearCard;
    PeriodCard periodCard;
    NameEmailCard nameEmailCard;
    //labels for cards
    private int currentLabel = 0;
    String classYearLabel = (""+1);
    String periodCardLabel = (""+2);
    String nameEmailLabel = (""+0);
 
    public void init() {
        //construct components
        cardLayout = new CardLayout();
        jcomp1 = new JLabel ("Main Page");
        nextButton = new JButton ("Next >");
        prevButton = new JButton ("< Previous");
        contentPanel = new JPanel ();
        classYearCard = new ClassYearCard();
        periodCard = new PeriodCard();
        nameEmailCard = new NameEmailCard();
 
        //adjust size and set layout
        setPreferredSize (new Dimension (415, 414));
        setLayout (null);
 
        //add components
        add (jcomp1);
        add (nextButton);
        nextButton.addActionListener(this);
        add (prevButton);
        prevButton.addActionListener(this);
        add (contentPanel);
        contentPanel.setLayout(cardLayout); //sets layout of contentPanel
 
        //set content layout
 
        //add stuff to panel
        contentPanel.add(nameEmailCard, nameEmailLabel);
        contentPanel.add(classYearCard, classYearLabel);
        contentPanel.add(periodCard, periodCardLabel);
 
        //set component bounds (only needed by Absolute Positioning)
        jcomp1.setBounds (25, 5, 100, 25);
        nextButton.setBounds (205, 320, 110, 25);
        prevButton.setBounds (85, 320, 110, 25);
        contentPanel.setBounds (15, 30, 300, 285);
    }
 
    public void start() { 
    }
 
    public void actionPerformed(ActionEvent e){
        if (e.getSource() == nextButton){
            currentLabel++;
            cardLayout.show(contentPanel, (""+currentLabel));
        }
        if (e.getSource() == prevButton){
            currentLabel--;
            cardLayout.show(contentPanel, (""+currentLabel));
        }
    }
 
    public void stop() {
    }
 
    public void destroy() {
    }
}

The code runs fine in the appletveiwer, so im guessing its the HTML, but i thought it would be better to post both
