Minecraft Server Mod
This is a server mod for the Minecraft Alpha server software. This is only the source code, if you don't know how to use this you won't find it useful.
Compiling
Add a new project from existing sources in whatever IDE you use. Add minecraft_server.jar as a library, and mysql-connector-java-bin.jar if need be. Your IDE should compile .class files that you can copy over into a clean minecraft_server.jar, then you can test your changes.
