[DGD] How to make a Java applet modify a web page

[Raymond Jennings]

Does anyone know how to have a java applet modify the web page that it's
on, and to make javascript calls?

What I'd like to do is build an interface that uses html, javascript, and
ajax to present a user interface, but keep a java applet running on the
page to maintain a control connection with the server.

This would allow information to be updated in realtime without having to
have the webpage do periodic refreshes.
