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?
