I'm doing applet-servlet (vice versa) communication aswell. I have jason
hunter's book which is v. good
but found his chapter on applet-servlet comm wanting. Here is a good link about
that same topic that you
might find interresting:
http://www.j-nine.com/pubs/applet2servlet/Applet2Servlet.html
It deals with object serialization very well indeed.

gerardo
