SimpleTableDemo needs to extend Applet to be run as an Applet.
The class declaration line should be changed from
public class SimpleTableDemo extends JFrame {
to
public class SimpleTableDemo extends JApplet {
or
public class SimpleTableDemo extends Applet {
You've also got to make some changes to the main method and override some
methods like the init() method.
I recommend reading through the tutorial on how to make applets on
java.sun.com.
