Error Log:

[Mr Green]

That's exactly the error I'm having. Running on a headless Ubuntu VPS, Java 1.6.

I've redownloaded the zip a few times, ran it as root; nothing seems to work. I'm starting to suspect the files in the zip might actually be corrupted, but that's unlikely considering everyone else isn't complaining.

[Diabloz]

try deleting the mod nether ores and see if it runs.

Forgot to mention I tried that. It ran, but not without multiple item conflicts, eg:

10:46:36 [iNFO] CONFLICT @ -204 item slot already occupied by net.minecraft.server.ItemWithAuxData@16ea269 while adding net.minecraft.server.ItemMobSpawner@68cb6b

You might need to reinstall java.

[ThCxProToTypE]

I have found a solution for this problem. You do in fact need the newest version of Java. That being Java 7 Update 5, but you have a obtain it a certain way.

This is what I did:

First go to http://java.com/en/download/chrome.jsp?locale=en (assuming you are you are using Google Chrome)

After you have done this, simply install Java from the file you just downloaded. Then your Tekkit server should run without errors.

The problem is that tekkit is using an older version of nether ores, the newest version is here

How to fix

1. Open the mods folder delete mod_NeatherOres.jar

2. Click here to download the latest version (direct link via dropbox)

3. Extract the GenerateNetherOres_Bukkit.jar to the mods folder

4. Run the launch.bat it will come up with an error

5. Open the config folder & open GenerateNetherOres.cfg in notepad

6. Change the Block ID to 135 & enableMaceratorRecipes to true

7. Save & close, & that's it

The problem was not NetherOres. It was java. As I previously explained.
