Start fireworks?

Three questions

1. Is there any possibility at the moment to start a firework?
2. Is there any possibility at the moment to create FireworkEffects/FireworkEffectMetas?
3. How can I edit NBTTags of items in 1.4.6 (without the new API)?

for 1.4.5 it worked

Code:

ItemStack item = new ItemStack(401);
CraftItemStack craftStack = null;
if (item instanceof CraftItemStack) {
    craftStack = (CraftItemStack) item;
    itemStack = craftStack.getHandle(); //the method getHandle() is undefined for the type CraftItemStack
}
else if (item instanceof ItemStack) {
    craftStack = new CraftItemStack(item); //the constructor of CraftItemStack(ItemStack) is not visible
    itemStack = craftStack.getHandle(); //the method getHandle() is undefined for the type CraftItemStack
}

imports:
import net.minecraft.server.v1_4_6.NBTTagCompound;
import net.minecraft.server.v1_4_6.NBTTagList;
import org.bukkit.craftbukkit.v1_4_6.inventory.CraftItemStack;
import org.bukkit.inventory.ItemStack;

maybe I have to wait for a newer build?

 

I would recommend waiting for a new build and see if they'll do i nifty way of setting off fireworks.
But you can still do it. (Dont know how )

 

PHP:

Player p = (Player) sender;
ItemStack i = new ItemStack(Material.FIREWORK, 64);
                FireworkMeta fm = (FireworkMeta) i.getItemMeta();
                List<Color> c = new ArrayList<Color>();
                    c.add(Color.BLUE);
                    c.add(Color.LIME);
                FireworkEffect e = FireworkEffect.builder().flicker(true).withColor(c).withFade(c).with(Type.BALL_LARGE).trail(true).build();
                fm.addEffect(e);
                fm.setPower(3);
                i.setItemMeta(fm);
                p.getInventory().addItem(i);

This is code gives a player 64 custom rockets. Works good.
I also tried to .spawnEntity(loc, EntityType.Firework); but that didnt work.

Using the latest beta build.

 

Firework spawning has not yet been implemented in Craftbukkit

 

https://github.com/Bukkit/CraftBukkit/commit/52e86815dbf0a002150eb3c44614c2ae7062e3e7 , I think this commit makes it possible now, doesnt it?

 

no this makes the entity spawnable but
