Throwing a weapon at something else

So I'm about three steps away from finishing my first sample game. But I need to figure out one last thing, and perhaps people here can help with it. I need my boss monster to throw his weapon at the hero. This involves two possible solutions: 1. Find the necessary rotation of the weapon in relation the the starting point and the hero's X, Y, which seems very difficult. or 2. Set the hero's current X, Y (at the time of the creation of the enemy's weapon) as the direction to move. Honestly, I remember trying to do this sort of thing when I first started out and it was a bust. I have no idea how to go about this. Anyone done anything like this?

Of use might be the Actor method 'turnTowards(int, int)' which sets the rotation of an object to point toward the world coordinates (x, y).

OH! I'd forgotten about that. Yes, that might be exactly what I need. Let me check.

Hm.. it's saying that the Hero's X and Y coordinates are non static and can't be referenced from a static context. I'm a real noob, so I'm going to try to translate that.. What it's saying is that the X and Y coordinates of the hero can't be applied to anything outside of the hero. Right? Probably because they change so often..

No. That is not what it is saying. What it is saying is that 'Hero' is a class name and the class does not have an X and Y coordinate (an actor created from the class and added to the world will, however). You probably are trying to use 'Hero.getX()' and 'Hero.getY()', when what you need is a reference to the Hero object that is in the world: 
Hero hero = (Hero) getWorld().getObjects(Hero.class).get(0);
// then
int heroX = hero.getX();
int heroY = hero.getY();
