Get dedicated server instance?

[SanAndreaP]

Is there a way to get a dedicated server instance? I need it for some entity manipulation in my GUI. This code works fine on the client:

FMLCommonHandler.instance().getMinecraftServerInstance()

 

but on a dedicated server, it gives me a null value. Here's my CommonProxy:

public class CSM_CommonProxy implements IGuiHandler {

@Override
public Object getServerGuiElement(int ID, EntityPlayer player, World world, int x, int y, int z) {
	List<Entity> entities = world.getEntitiesWithinAABB(CSM_EntityClayNexus.class, AxisAlignedBB.getBoundingBox(x, y, z, x+1D, y+1D, z+1D));

	for(Entity entity : entities) {
		if (entity != null && entity instanceof CSM_EntityClayNexus) {
			return new CSM_ContainerNexus(player.inventory, (CSM_EntityClayNexus)entity, ID == 0);
		} else {
			return null;
		}
	}

	return null;
}

public Object getClientGuiElement(int ID, EntityPlayer player, World world, int x, int y, int z) {

	List<Entity> entitiesC = world.getEntitiesWithinAABB(CSM_EntityClayNexus.class, AxisAlignedBB.getBoundingBox(x, y, z, x+1D, y+1D, z+1D));

	} catch (NullPointerException e) {

	}



	CSM_EntityClayNexus clientEntity = null, serverEntity = null;

}

public boolean isClient() {

public void registerRenderInformation() { }

public void showEffect(String effect, Object... data) { }

}

Try the modsloader one, or use a variable that gets initialized @ServerStartup, I use the variable style, I found it works better and it looks cleaner, but that is opinion.
