Source please

Of the mod?

Yes, the mod

There's about 40 files. Okay, send a pm.

What about CommonProxy?

EDIT: Server don't want to start in eclipse because it says:

2013-02-01 14:33:49 [sEVERE] [Minecraft] Encountered an unexpected exception NoClassDefFoundError

java.lang.NoClassDefFoundError: net/minecraft/src/Render

In CommonProxy you need to put the same methods returnig either nothing or null and in clienproxy you put the same methods but with what the client should return or do. for as far as I know, if you do it correctly, it will automaticaly take clientproxy on client side and common proxy on the server side, if not you might end up that it uses CommonProxy for both.

Now I notice what mcp and Forge not decompile minecraft_server.jar and Render.java don't found on server. But why?

But anyway, why do I get the error
