SOAP xml response received but not populating response object

Question

I added a "Service Reference" to a vendor\'s Java based web service which i have no control over.

I have this simple client code:

   Client m         


        

Answer 1

I was able to figure out my problem: There was a namespace mismatch.

The body of my request soap envelope contained:

<csw:GetCapabilities 
xmlns:csw="http://www.opengis.net/cat/csw/2.0.2" 
xmlns:dc="http://purl.org/dc/elements/1.1/" 
xmlns:dct="http://purl.org/dc/terms/" 
xmlns:sch="http://www.ascc.net/xml/schematron" 
xmlns:gml="http://www.opengis.net/gml" 
xmlns:ogc="http://www.opengis.net/ogc" 
xmlns:ows="http://www.opengis.net/ows" 
xmlns:xlink="http://www.w3.org/1999/xlink" />

In the response i was getting (top relevant characters only):

<wrs:Capabilities xmlns:wrs="http://www.opengis.net/cat/wrs/1.0" xmlns:csw="http://www.opengis.net/cat/csw" xmlns:ogc="http://www.opengis.net/ogc" xmlns:ows="http://www.opengeospatial.net/ows" xmlns:xlink="http://www.w3.org/1999/xlink" version="1.0.0">

Notice how the OWS schema namespace in the REQUEST is pointing to http://www.opengis.net/ows

While the response is pointing to http://www.opengeospatial.net/ows

Both namespaces have to be the same for .NET to deserialize the data. So you could just have the response respond the correct namespace. In my case, since i had no control over the Java Web Service, i had to modify the auto-generated proxy class and replace all instances of “xmlns:ows=http://www.opengis.net/ows” for “xmlns:ows=http://www.opengeospatial.net/ows”

Answer 2

Maybe you might try to generate a client proxy using SvcUtil instead of using a service reference. I am unaware as to whether they would generate the same client code, but you might as well try it anyway.
