Your testsite.get() method will return a class, not an object (instance of a class). You can't call a non-static (instance) method for a class. You can either change the get method to a static method, or instantiate an object (using new) to access it.
Give a man a fish, he'll eat for one day. Teach a man to fish, he'll drink all your beer.
