Java chat server - release 1

http://forums.devshed.com/showpost.php?p=2113904&postcount=34

Read it, play with it, have yourselves some fun.

I will for a while leave my server on. Don't expect me to actually be checking anything or being online to talk to you.

I'm posting this in the lounge because it's really easy to just run this yourselves for whatever reason you want. No need for java expertise.

Hmm, maybe I should have a license for the program or something. Don't really care because nothing is groundbreaking.

Edit:
Developers, look into
ServerController.processAuthRequest(Packet p, AccountHandler source) to find out how to make a real login instead of just username same as password.

mikeyskona agrees: Nicely done

.. could turn in to a very nice chat app. Maybe DevChat? hehehehe

Todo list:

Shut down server command needs a small pause to allow clients to exit gracefully, as well as some slight tweaks.

Enabling user-pass control - when a client sends a packet, make sure it has the user-pass right. I don't see any way that it would hurt if it wasn't, but I don't see everything. Currently once you login you can send a packet and the server automatically gives you the right username etc.

Spam filter. Yeah.

Patcher. That's already in the works. This way when you connect the server will send you any patches necessary; program closes and you connect again.

Oh, and possibly a logout function... don't really want to though, too much hassle to log out and back in, just close the bloody program.

Edit: Oh, and make username/roomname comparisons ignore case. Forgot about that.

Why in the blazing hell do you have 1.4? I use generics, I don't think 1.4 can even support my program. Upgrade your slow *** to 1.6

Nicely done

I think gimp ought to alter the code so you don't have to run this from the same directory. I don't have the "java" enviroment variable set (I just set it and I have to reboot my machine for it to be active) so I have to run from the java bin directory. When I get an open chance I might reboot so I can check it out though.

(btw vista doesn't let you have spaces when typing in the full path to a program, it thinks your trying to send it arguments)

Should work

also cd "c:\path to a folder\with spaces in it\ whatever" should work tho

I just tried it with the quotes (didn't know I could do that!), but now i just get this

C:\Users\Danny\things\chat>cd "C:\Program Files (x86)\Java\jre1.6.0_05\bin\java.
exe" Driver
The system cannot find the path specified.

I think I may just have to reboot, I might go do that soon
