Java: Telnet Chat Server

I have created a telnet chat server in Java.  To connect to your server, just type:

Code:

telnet [your ip address]

in command prompt/terminal/whatever you call it.
How to set up a server
1) Download JTelnetChat.jar to an empty folder.
2) Type the following in notepad and save it as a .bat file in the same folder:

Code:

@echo off
java -jar JTelnetChat.jar

3) Run your new file
4) Try it out
5) Stop your server and edit motd.txt
6) (If you want) edit the banlist (IP addresses, delimit with whatever you want.)
7) Run your server again.
Downloading
1) JTelnetChat.jar
Source:
1) JTelnetChat.zip

Re: Java: Telnet Chat Server

Nice. But wouldn't there be a problem with the fact that telnet easily disconnects?

I'm back.
Maybe.

How would that be a problem?

Try recompiling from the source... that seems like a compiler error rather than an error on my end...

You need to update to Java 7 or compile it for Java 6.

Cool.

I play a text-based game with telnet once and it kept disconnecting every minute or two. I think it was actually the first or one of the first telnet Multi-User Dungeons or something like that.

So that's what that means!  That happened on my friend's computer once, too.
