Subject: RE: Servlet to Applet Dynamic Updating
Thanks so much Kevin. So by client-side socket you mean set up a Socket
type component within my applet? Furthermore, this is not going to be on
the Internet it's just in a LAN so I wouldn't have to worry about firewalls.
Because of this would I still use java.net.HttpURLConnection? Finally,
could I get rid of the applet part in my system and just use a servlet to
display real time graphs and charts on a client-side computer or would I
need an applet for the necessary GUI's?

You can't open a server-side socket in an Applet. You can open a client-side
socket and read from the server (or have the server write to you), however,
the problem then becomes the port you want to use.
If the server sits behind a firewall, it may only allow incoming connections
on port 80 (http), so you'll probably need to talk to a servlet/jsp/asp/cgi
script, and if you are going to do this you may as well use
java.net.HttpURLConnection.
BTW, this as nothing to do wth servlets and shouldn't really be posted to
this list :-)
