I have a JSP which is divided into 2 side-by-side frames.

You can proceed two ways

  1. Make the "addNode" and "removeNode" buttons applets themselves. (Not the best idea)
  2. Create a hidden applet in the frame you have the buttons; and use Javascript to communicate with it. Here is a posting in the Applet FAQ that talks about communication between JavaScript and an Applet.
Look through more of the FAQ posts here on JGuru to find more techniques.

I had a lot of fun getting Applets to communicate with my browser and applets communicating between applets.

Hope this helps
