running java class on website

Question

I have created a java program using Eclipse and am attempting to run it online (it's a simple game). I have the .class file working on it's own and the program runs end to end with no problems. I have problems when I try and run it on the website. I have used the following code to attempt to launch it as an applet with no luck:

When I goto the website it tells me to click on the applet for details. When I do that, I get a popup that gives me a RuntimeException of: java.lang.reflect.InvocationTargetException

What are the steps that I am missing to get this running? Both the Handler.class and the Handler.jar are in the same location.

The main menu java code is as follows:

/*
 * Main Menu is the start up window that is displayed when the program starts. It has one button, "Start Game", and a randomly
 * selected picture from a batch of 6. 
 * 0->23
 */
