Problem with running mod on a server

[telinc1]

Well, I have a nasty problem. From Eclipse and go to Run -> Server the Minecraft Server opens, but it prints out the following error:

And it fails to run. I'm sure it's a problem from my mod, but I have no idea how to fix it. Any help is appriciated, thanks in advance!

 

P.S.: This also happens if I decompile, reobfuscate and put it on a normal server.

i have been getting the same problem, hope someone works out why

You have a hard reference to a client only class, namely WorldClient, remove that hard reference...

Well, I searched around all files from project Minecraft and the only place I found "WorldClient" was on line 29 at cpw.mods.fml.common.modloader.BaseModProxy:

import net.minecraft.src.WorldClient;

 

Where else could this thing be?

Its referenced in your mod somewhere. You'll have to find it, we're not gunna dig around your code telepathically for you..

Strange, but right after I ran a global search for the class, the problem fixed itself and then I just needed to play around with ModLoader.addArmor(); to make it work and the server is okay. Or at least the test server only... I will see about the real one. But thanks anyways.
