David,
You cannot send an element of an abstract type. Your choices:
- don't send the <Address/> element (requires minOccurs="0")
- define it as a concrete type

I am testing some interoperability between a Java Client using Axis and
a .NET ASMX Webservice and am experiencing a problem and was wondering
if anyone has an idea of what is going on.
If I have a class that contains a data member that is abstract and try to
pass a
derived class type into the webservice, an XML error is generated. If I
receive the
same exact structure from the webservice all works as expected.
I have a full .NET webservice and java client that will demonstrate the
issue if
anyone wants the code.
I am including the soap messages that are received on the service.
The class definition follows the SOAP Messages.
Thanks,
Dave
