Java Applet HelloWorld "Getting Started With Applets" example not working

Hi there,

It's been ages since I ran my Linux CentOS boot of Linux but I am going through the official oracle java applet tutorials, just every time I try and run the "Hello World" applet in Firefox 17.0.3 and I am running the Iced Tea thing for java applets.

Every time I try and run the example from the following code:
import javax.swing.JApplet;
import javax.swing.SwingUtilities;
import javax.swing.JLabel;

public class HelloWorld extends JApplet
{
  
  // called when the user enters the html page:
  public void init() // keep apps within the init() function very small as per the http://docs.oracle.com/javase/tutorial/deployment/applet/appletMethods.html
  {
    try{
      
      SwingUtilities.invokeAndWait(new Runnable()
      {
        public void run()
        {
       JLabel myLabel = new JLabel("Hello World");
       add(myLabel);
        } // end running the application
      }); //end of swing invokeand wait
    } catch (Exception error){ // end user running the app in page
       // System.err.println("GUI didn't work on initial run");
    }
  }
}
It keeps bringing up the error "Start: Applet not initialized" I did google that basic error and from what I found I should consult the JavaConsole, I know the console was removed from the Firefox menu quite a while ago. So went to find a way of loading it using the IcedTea one but it keeps bringing up a load of errors in even trying to run that.

Is there anyway of sorting this out? I mean I have even tried installing the one on the oracle website, the plain JDK but nothing seems to work.

Is there anyone that can help me get applets working? I was even going to go as far as to reinstall my distro but I want to avoid that as much as possible.

Thanks and I look forward to any replies,
Jeremy.
