Thanks everyone who helped us out!
We were able to get Applet-Servlet communication going OK,
running with AppletViewer and Java Web Server.
Of course, at the end of the party, we now face the next issue:
For some reason, while it works ok when we run with AppletViewer,
if we do the same thing from IE, we get a security exception (messages
pasted below). We have tried connecting to a server on the same machine
and also a different machine (as suggestd in the forum).
Thanks in advance,
