Why can't I compile Java applets?

[CaptainCheeseTits]

I started learning java and since I have lots of web building experience, I want to start by learning how to make applets. I found some hello world applets here:
http://muq.org/~cynbe/java/classes/hello/hello.html
to play with. They run fine when I view them on that website but when I compile them myself and run them on my local apache server, heres what happens:

heres the details:

I'm using the official version of JDK 7 that I downloaded from the Oracle website:
http://www.oracle.com/technetwork/ja...d-1501626.html
any idea what I could be doing wrong?

BTW heres the code:

import java.applet.*;
import java.awt.*;

public class HelloWorld extends Applet {
    public void paint( Graphics g ) {
        g.drawString("Hello World",50,25);
}   }

thats about as simple as an applet can get, how could it be going wrong?

Update your JRE.

Will do but how come it could run it on the external website, but not my own internal webpage. I thought that when you visit a site with an applet, your browser downloads the .class file and executes it locally.

I updated JRE and now it works. Thanks.

The external site's applets were converted into bytecode with an older version of java that conveniently worked with your old JRE.

A horrible troubleshooting coincidence.
