My simple mod:

 

package net.minecraft.src;

import net.minecraft.src.forge.NetworkMod;

public class mod_EhCoin extends NetworkMod
{
public static Item ehCoin_Bronze;

public mod_EhCoin(){}

public String getVersion() 
{
	return "0.1";
}

public void load() 
{
	ehCoin_Bronze 	= new ItemEhCoin(3500).setItemName("EhCoinBronze");		
}

public boolean clientSideRequired()
    {
        return true;
    }

    public boolean serverSideRequired()
    {
        return false;
    }
}

 

 

What can be this?

 

 

So.. you're trying to run a vanilla mod on a bukkit server, the hell makes you think that'll work?

I do not know, I tried searching for how to Bukkit, but not found.
