New to Java

I don't know where to post this so I will try here. New to Java.
This has bugged many of us who use Anfy applets on our web sites.
Since most computers these days have the sun java on their systems Anfy applets no longer seem to work and our pages get a red X and we do not know what to do to correct the problem.
Example I am working on a page with a simple fade applet by Anfy for another anfy applet user here
http://cmcamper.com/anfy/linda/1.html
I get a general error message box that pops up.
It says:
Name:Anfade
java.lang OutOfMemoryError: Java Heap Space.

It also blocks the applet from loading and gives a red X
The status bar says Applet Anfade notinited

This has been quite frustrating and we all seem to not be able to find an answer to the problems sun has had on our web pages using the anfy applets from anfy.com

Is there a simple solution where we can get our applets to work where visitors to our sites do not have to go into sun and make changes and simply be able to view our applets like in the past?

I hope someone can be of help to this big issue we all have.
