That doesnt make sense. If I have getCats() and getDogs(), then look at the wsdl, it creates a type Animal then, then has Cat and Dog that extends it. How non object oriented languages handle it is their own business, but the wsdl allows hierarchies as do the the SOAP messages. That being said, can I expose the base class in my interfaces and the wsdl will generate the correct complex types for all of its subclasses?
