Response of a Web Service developped in C#

Question

Hi all,
I am trying to call a Web Service from XI. For this I imported the WSDL file of this Web Service as an external definition. The problem I have is that the person who develops this web service returns a structure of type "Dataset" in C#. In the WSDL file, the response part looks like this :
<s:element name="GetDB2DataResponse">
<s:complexType>
<s:sequence>
<s:element minOccurs="0" maxOccurs="1" name="GetDB2DataResult">
<s:complexType>
<s:sequence>
  <s:element ref="s:schema" />
  <s:any />
  </s:sequence>
  </s:complexType>
  </s:element>
  </s:sequence>
  </s:complexType>
  </s:element>
So when I try to map the return of the Web Service, I only have one field in the Message : NewDataSet of type "xsd:schema", and I can't do any mapping with this.
I don't know C# so I don't know how the WS developper could change the return type.
Does any of you know what kind of structure the Web Service should return if I want to have the complete return structure at design time ?
Thanks in advance.
Best regards,
Julien

Hi Julien,
No way to work with that generic "schema".
I think in the WSDL you should have the schema as well. Just like the way XI exports message interfaces into WSDL: you can try yourself, and you'll notice that, if you have a synch interface for instance, both input and output messages definitions are inside the wsdl as xsd's.
More, from what I can understand, "GetDB2DataResult" sounds like you'll be returned a set of tb rows, so in my opinion you should get back to the C# guy and tell him to complete the wsdl with missing infos.
If he can't provide this info, so just go calling the ws, see what's inside the returned message and create the matching data type yourself.
Hope this helps.
Best wishes,
