Wolf does not attack?

Hello Minecraftians/Bukkitters!
I'm currently creating a Boss Plugin, and one Boss makes a wolf spawn everytime the boss is attacked, which is supposed to attack a random player.

So, I now have this code:

Code:java

        if (e.getEntity() == TheHoundmaster){
            LivingEntity entity = (Zombie) TheHoundmaster;
            if (entity.getHealth() <= 10 + e.getDamage()){
                Location[] jails = new Location[] {
                    new Location(hideout, 63, 4.5, 1211),
                    new Location(hideout, 49, 4.5, 1217),
                    new Location(hideout, 49, 4.5, 1211),
                    new Location(hideout, 63, 4.5, 1217)
                };
                Wolf w = (Wolf) hideout.spawnEntity(jails[(int) (Math.random() * 3)], EntityType.WOLF);
                w.setAngry(true);
                w.setCustomName("Angry Wolf");
                Player random = hideout.getPlayers().get((int) (Math.random() * hideout.getPlayers().size() - 1));
 
            }
        }

How do I make the Wolf attack Player "random"?

I already tried .setTarget(random), but the wolf still did nothing.
And I tried w.damage(0,random), but from unknown reasons the wolf dies immediately.
So, any ideas how to fix it?

 

Gabum I know there has been issues with this before, but this may be a useful resource to check out: http://forums.bukkit.org/threads/entity-pathfinding-and-targetting.103322/

 

Would something be possible like setting the Houndmaster as the owner of the dogs?
