Need help converting complex Swing App to Applet

[Matt Wil]

Hi,
Have an swing application that uses JFrame, JSplitPanes, a lot of JPanels etc..
Are there any good guides on the web on how to convert a swing application to applet?
My main class file creates a window(JFrame) with:
window = new FrameSet("Name Here");
I assume just the main class needs to extend JApplet? My FrameSet class does not?
When I run the program by simply switching main to init, I get applet notinited.
Thanks in advance!
