I have a webservice (out of my control) that I have to talk to. I also have a packet-sniffer on the line, and (SURPRISE!!!) the developers of the webservice aren't lying.
They are actually sending back all of the data that I requested. But the web-service code that is auto-generated from the WSDL file is giving me "null" as a value.
I used their WSDL file to generate my Web Reference. I checked my data types with the datatypes that the WSDL file has declared. And I used the code as listed below to perform the calls:
DT_MaterialMaster_LookupRequest req = new DT_MaterialMaster_LookupRequest();
req.MaterialNumber = "101*";
req.DocumentNo = "";
req.Description = "Pipe*";
req.Plant = "0000";
MI_MaterialMaster_Lookup_OBService srv = new MI_MaterialMaster_Lookup_OBService();
DT_MaterialMaster_Response resp =
srv.MI_MaterialMaster_Lookup_OB(new DT_MaterialMaster_LookupRequest[] { req });
// Note that the response here is ALWAYS null!!
Console.WriteLine(resp.Status);
The resp object is an actual object. It was generated properly. However, the Status and MaterialData fields are always null.
When I call the web service, I've placed a packet-sniffer on the line, and I can see that I've sent the following (linebreaks and indentions for my own sanity):
<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<soap:Body>
<MT_MaterialMaster_Lookup
xmlns="http://MyCompany.com/SomeCompany/mm/MaterialMasterSearch">
<Request xmlns="">
<MaterialNumber>101*</MaterialNumber>
<Description>Pipe*</Description>
<DocumentNo />
<Plant>0000</Plant>
</Request>
</MT_MaterialMaster_Lookup>
</soap:Body>
</soap:Envelope>
The response that they send back SEEMS to be a valid response (linebreaks and indentions for my own sanity):
<SOAP:Envelope xmlns:SOAP='http://schemas.xmlsoap.org/soap/envelope/'>
<SOAP:Header />
<SOAP:Body>
<n0:MT_MaterialMaster_Response
xmlns:n0='http://MyCompany.com/SomeCompany/mm/MaterialMasterSearch'
xmlns:prx='urn:SomeCompany.com:proxy:BRD:/1SAI/TAS4FE14A2DE960D61219AE:701:2009/02/10'>
<Response>
<Status>No Rows Found</Status>
<MaterialData />
</Response>
</n0:MT_MaterialMaster_Response>
</SOAP:Body>
</SOAP:Envelope>
The status shows that it actually received data... but the resp.Status and resp.MaterialData fields are always null. What have I done wrong?
UPDATE:
The WSDL file is defined as:
