Hi Shaun
there are some different ways to implement servlet/applet communication.
One way is using sockets and exchanging text based information or serialized
Obejcts. The other way is using RMI.
For a deeper intorduction take a look at 'Java Servlet Programming' by Jaosn
Hunter, published by o'reilly and available in brief with sample source code at
http://www.servlets.com/jsp/examples/ch10/index.html - anyway: the book is worth
buying it ;-)
Hope, that helps,
Rupert
