I need help with Applets

Trying to learn how to use applets, i hope this is the correct place to post! If it is not please direct me to the correct place and I will post there (and delete this one if i can)

where to begin....

When i try to open up the website i get this error in the java console:

I have this code in my .php file:

Code:

---

<applet archive = "HelloWorld.jar"
            code= HelloWorldApplet
            width="98%"
            height="900"
            alt="ATVe is not working on your system (requires at least Sun Java 1.5)!">
</applet>

---

in the directory i have:

index.php (which contains my applet code and some titles etc.) and HelloWorld.jar which contains:

jar tf HelloWorld.jar
META-INF/
META-INF/MANIFEST.MF
HelloWorld/
HelloWorld/.DS_Store
HelloWorld/HelloWorldApplet$1.class
HelloWorld/HelloWorldApplet.class

I am a little suspicious about that $1.class....but i do not know that much about java (it got created because of an annonymous inner class? probably something to do with using GUI or JApplet)

my HelloWorldApplet class looks like this:

Code:

---

package HelloWorld;

import javax.swing.JApplet;
import javax.swing.SwingUtilities;
import javax.swing.JLabel;

public class HelloWorldApplet extends JApplet {
    //Called when this applet is loaded into the browser.
    public void init() {
        //Execute a job on the event-dispatching thread; creating this applet's GUI.
        try {
            SwingUtilities.invokeAndWait(new Runnable() {
                public void run() {
                    JLabel lbl = new JLabel("Hello World");
                    add(lbl);
                }
            });
        } catch (Exception e) {
            System.err.println("createGUI didn't complete successfully");
        }
    }
}
