Development Assistance Setting NBT data on mobs

Hey there!
I'm making a plugin that requires me to have mobs that don't move. And with don't move I mean that they should be like statues, no gravity, no AI and they should always look in the same direction. Now in 1.8 there is this NBT data tag thats called NoAI and it does exactly that. My question is, how do I set the NoAI-NBT data of of a skeleton from 0 to 1? is it done with setMetaData? I have no clue.

 

@Fruitninja567 If there's no Bukkit method for it, there's a simple but dirty way to do it. Get the UUID of the entity, then do Bukkit.dispatchCommand(Bukkit.getConsoleSender(), "entitydata "+id+" {NoAI:1}");

 

Hmm, tried it but it doesn't work for me, did I do something wrong?
I did this:

Code:

       Entity en = b.getWorld().spawnCreature(b.getLocation().add(0.5,-1,0.5), CreatureType.SKELETON);
       Bukkit.dispatchCommand(Bukkit.getConsoleSender(), "entitydata " + en.getEntityId() + " {NoAI:1}");

Whereas b is a block.

EDIT: Nevermind, Thank you! I changed it to getUniqueID() it works now.
