Your interface has a type parameter with no upper bound so it is effectively Object. Thus GWT does not know which classes to scan because it will not scan every subclass of Object. Either give your type parameter an upper bound using a common interface or create a dummy method in your service interface that returns a dummy class which references all your classes you want to use in your load method.
