Applets are very different from applications,
and if you are uncertain of that, it probably
means you would be better to post to a group
for Java starters. More details here..

But then, people who are just learning Java
should not be attempting applets, and somebody
doing a chat server should probably develop it
as an application 1st, just to cut down on
development time.

Then start using it.

Please begin -- now -- to express yourself in complete, grammatically
correct, sentences. This will assure that you will be understood. Then
someone can offer advice based on what your actual question is.

andrew gave you some good advice. Based on the several posts of yours I
have read, I would suggest you take about twelve steps backwards and
develop some basic skills before you tackle a chat program. You will
need to have a good understanding of threads, serversockets, if streams,
just to name a few. Try reading a few books and working through the
sample programs.

Also, this is a forum for specific problems with code -- try
comp.lang.java.help for more general questions

good luck!

Yes. What marcus wrote.

please don't top post, and stop agreeing with me

Marcus, please don't top post when correcting top-posters. It is
disengenuous. Also, font related posts should probably go to
comp.lang.java.gui.

...now, where did I leave
that damn 'font'?

Unsigned Java applets can only connect back to the URI from which they were
loaded, they can not connect directly to each other. In other words, two
users can not download a Java applet from the same Web server and
automatically connect and chat with each other. In fact, without some help
from the (a) server, the two Java applets won't even know there is another
Java applet out there to chat with.

As a result, in order to make a multiuser chating program using java applet,
you need to have a _server *application*_ somewhere (probably on the HTTP
server that served up the applets) for them to connect to. This server would
take care of authenticating the various applets, and relaying the text typed
on one applet to all the other applets that are connected to the server.

This server application could be written in Java, or it could be written in
some other language, it would not matter as long as it understands how the
Java applets connect, authenticate and exchange data.
