[1.2.5](Forge 3.4.9.171) Entity Invisible in SMP

Hi, i'm a french noob in modding!

I make my first mod with gun and ammos, and everything works in clientside.

But when I rightclick on my gun my Entity is invisible in serverside.

I know then I forgot a lot of things but what?

I show you:

 

ClientSide

 

mod_Gun

 

package net.minecraft.src.gun;

public class mod_Gun extends NetworkMod

{

public static String textureSprite1 = "/gui/mods/items2.png";

    public static final Item Weapon = (new ItemWeapon(2051)).setItemName("Weapon").setIconIndex(144);

    public static final Item Ammo = (new ItemAmmo(2052)).setItemName("Ammo").setIconIndex(145);

 

public void load()

    {

ModLoader.addName(Weapon, "Weapon");

ModLoader.addName(Ammo, "Ammo");

MinecraftForgeClient.preloadTexture(textureSprite1);

ModLoader.addRecipe(new ItemStack (Weapon, 1), new Object[]{

" # "," # ","# #", Character.valueOf('#'), Block.dirt});

ModLoader.registerEntityID(EntityAmmo.class, "Ammo", ModLoader.getUniqueEntityId());

ModLoader.addRecipe(new ItemStack (Ammo, 5), new Object[]{

"###","###"," # ", Character.valueOf('#'), Block.sand});

}

 

public void addRenderer(Map map)

    {

        map.put(EntityAmmo.class, new RenderAmmo(Ammo.iconIndex));

       

    }

 

 

    public String getVersion()

    {
