[1.7.2] [Solved]How to associate item with custom entity

So when I shoot  with my item, I spawn entity

code in Item's class to spawn entity

            if (!par2World.isRemote)
            {
                par2World.spawnEntityInWorld(entitybullet);
            }

if entitybullet is equal to EntityArrow, Arrow spawns succesfully.

if entitybullet  is equal to my custom EnitityBullet I shoot with nothing! I have by bullet Item with working texture. How can I associate my Entity with my Item to shoot with Bullet.

I am sure that in Entity's class not described how it looks like.

Solved. Just need to register and render Entity http://www.minecraftforum.net/topic/1892995-rendering-your-custom-item-texture/
