Include Schema Type in WSDL file

Question

I created a WSDL by hand that has only one operation with no input parameter and no output parameter.

I am getting following error when I try to create a client from this WSDL:

Cannot import wsdl:portType Detail: An exception was thrown while running a WSDL import extension: System.ServiceModel.Description.DataContractSerializerMessageContractImporter Error: Schema with target namespace 'http://www.xmlns.mycompany.com/GAME/service/Associate/1.1/' could not be found. XPath to Error Source: //wsdl:definitions[@targetNamespace='http://www.xmlns.mycompany.com/GAME/service/Associate/1.1/']/wsdl:portType[@name='GAMEAssociateIntf'] C:\toolbox\BlueTest\BloodRedTest\BloodRedTest\Service

The types (to be used in the client) need to be generated from the XML present in the WSDL. I think, while adding Service Reference, the tool is failing to create it due to some error in the XML. The xsd seems to be the issue.

What change need to be done in the WSDL to create the proxy ?

Note: I am trying to include the xml types defined in WSDL itself. [I don't need a separate file for schema defenition]

WSDL

Answer 1

I spent some time trying to find out issues. Your <types> section of the wsdl is incorrect, it should be like below. With this, I can now generate client side artefacts in Java.

<types>
<schema targetNamespace="http://www.xmlns.mycompany.com/GAME/service/Associate/1.1/"
          xmlns="http://www.w3.org/2001/XMLSchema">
   <element name="myData">
     <complexType/> 
   </element>

   <element name="myDataResponse">
     <complexType/>
   </element>
</schema></types>

UPDATE

Based on the conversation below. Added a nillable attribute.

<element name="myDataResponse" nillable="true">
<complexType/>
</element>
