Include Schema Type in WSDL file - wcf

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]

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>
Request
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns="http://www.xmlns.mycompany.com/GAME/service/Associate/1.1/">
<soapenv:Header/>
<soapenv:Body>
<ns:myData/>
</soapenv:Body>
</soapenv:Envelope>
Response
<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
<s:Body xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<myDataResponse xsi:nil="true" xmlns="http://www.xmlns.mycompany.com/GAME/service/Associate/1.1/"/>
</s:Body>
</s:Envelope>

Answer 2

wsi.org has a set of validation tools, which would certainly be worth trying.
The added benefit of using these tools is that you can then actually claim compliance with the WSDL specification(s).

Answer 3

I referred Inline Schema. Thanks to #Indoknight also. The working contract WSDL is given below.
Note1: The xsd prefix and targetNamespace is there in the schema that is used inside wsdl type
Note2: nillable="true" is applied for the type used in the response message
Note3: If you are getting following exception, make sure that the soapAction is exactly same in the contract WSDL and the wsdl generated from WCF service. Some tools used for generating Service code may modify the SOAP action at it’s own will.
Faultcod: a:ActionNotSupported
Faultstring: The message with Action 'http://www.xmlns.mycompany.com/GAME/wsdl/AssociateIntf/1.4/getAllVicePresidentsRequest' cannot be processed at the receiver, due to a ContractFilter mismatch at the EndpointDispatcher. This may be because of either a contract mismatch (mismatched Actions between sender and receiver) or a binding/security mismatch between the sender and the receiver. Check that sender and receiver have the same contract and the same binding (including security requirements, e.g. Message, Transport, None).
