I'm guessing your exception is a ClassCastException because the actual class is AnyTypeDataObjectImpl, and not PersonImpl. For the DAS to create instances of your generated class it would a) have to be using the default helper context, and b), understand that Person objects are from the http://www.example.org/person namespace. Perhaps someone who is familiar with DAS could take a look at this?
