SMP 1.3.9 No Mod World Gen

[inittowinitall]

Hello. I am creating a new Big Dig server for my friends and I to play on, but when I create a new world, there is no world gen at all. Tree cap does not work either although rei 's minimap and NEI work perfectly. NEI even has all the mod recipes. Any help would be appreciated.

I have discovered the error in my ways. I realized that I needed to run bigdig.jar and not minecraft_server.jar.
