auss I successfully wrote my chat program and you can find the thread here:
http://www.javaprogrammingforums.com...n-process.html
(the last post shows the correct complete program)
-you open the chat and it will wait on a certain port number through a serversocket
-you open the chat on a second machine and you choose to call out, using the IP of the first machine...
