How Do I Spawn Experience Orbs?

Anyone know how to spawn experience orbs and drop them like items? The way I do it is deprecated and so it doesn't work with 1.2.5. :C

 

Try world.spawn(location, ExperienceOrb.class);

 

Yup, I'm using it right now and it's not working, although its not giving me any errors either. Heres the code:

Code:

                  float Exp = playerquit.getExp();
                  int ExpOrbs = (int) Exp;
                  ExperienceOrb orb = null;
                  World world = playerquit.getWorld();
                  ((ExperienceOrb)world.spawn(playerquit.getLocation(), ExperienceOrb.class)).setExperience( ExpOrbs );

Update: It IS working. But I can't seem to make the player drop ALL their Exp. As of now, they only drop Exp equal to one level. Their overall level stays the same. :C

Update: It works now! I used the experience/level equation to find the how much exp should be dropped and then set their level to zero. Thanks.
