Help referencing the player server-side?

I've been using:

 

EntityPlayer player = (EntityPlayer)event.entity;

or:    EntityPlayer player = Minecraft.getMinecraft().thePlayer;

 

in my code, but when I try to test it on a server, I get an error on this line in my main class:

 

public static final KeyHandlerEvents keyBinding = new KeyHandlerEvents();

 

saying:      java.lang.NoClassDefFoundError: net/minecraft/client/entity/EntityClientPlayerMP

 

The content of that class is in the spoiler at the bottom.

 

The rest of the error is here if it matters:

Before I added anything that uses EntityPlayer player = (EntityPlayer)event.entity; or EntityPlayer player = Minecraft.getMinecraft().thePlayer; it worked fine on servers, and in single player it works perfectly fine as it is now, so how exactly do I reference the player on a server if not either of those?

 

The class it's pointing at now is this if someone needs to see the whole thing. There's probably other places, but I can't check until this one passes startup:

Hi

 

You might find this useful for getting the player on the server side

http://greyminecraftcoder.blogspot.com.au/2013/10/server-side-class-linkage-map.html

 

Using EntityPlayer player = Minecraft.getMinecraft().thePlayer on the server side will either fail outright or lead to intermittent bugs/crashes if the server thread accesses a client object at the same time as the client thread.
