Subject RE: Polymorphism in Web Services (badly need help here)
Date Thu, 12 Jun 2003 18:56:28 GMT
FWIW:

Microsoft's MapPoint Web Service uses a little polymorphism.
(http://staging.mappoint.net/standard-30/MapPoint.wsdl)

Though it didn't run without problems, the Axis v1.0 WSDL2java did properly
create the mappings for MapView and it's descendants, though they're
relatively simple objects.
