Ok, so I'm trying to run Omen/Minecraft server. Currently my folder looks like this:
$ ls
Omen - Read me.txt    minecraft-server.jar    start server.bat
Omen060.jar        runOmen.bat
README.TXT        runOmen.rtf

When I open Omen060.jar or minecraft-server.jar as Java applications, it tells me that it could not be launched and to check Console for errors. Errors:

Attempting to run the Omen.bat results in Terminal responding with:
$ /Users/siretrm/MyApps/minecraft-server/runOmen.bat ; exit;
Exception in thread "main" java.lang.NoClassDefFoundError: net/minecraftforums/osici/Omen

Help? Is there as .sh Shell Script to work this like with World of Minecraft Client?

Thanks, TRM.
