Question

I have been trying to generate a Proxy class in VB.NET using a WSDL file for an Apache Axis SOAP Web Service.

They have provided me the WSDL file and when I use the WSDL.exe command (In Visual Studio 08) and point it to the local path I get an error.

wsdl /language:vb c:\Orders.wsdl

(I am trying to create a .NET Client that consumes the SOAP Web Service Hosted on Apache Axis 2)

The Error

Unable to import binding 'OrdersSoapBinding' from namespace 'urn:company:orders:schemas:OrderTypes:1.00'.

-Unable to import operation 'placeOrder'

-The element 'urn:company:remtp:schemas:PlaceOrderRequest:1.00:PlaceOrderRequest' is missing

if you would like more help, please type 'wsdl /?'

If I use the svcutil.exe I also get an error message…

svcutil.exe C:\Orders.wsdl /t:code /l:VB /o:"C:\Orders.VB"

What is causing the problem?

Your help will be much appreciated, Thank you.

Looking into the wsdl file you provided, You’ll see references to four xsd (xml xchema document) files: they contain the type definitions and validation rules needed by svcutil to create the proxy.

   <import namespace="urn:company:remtp:schemas:PlaceOrderRequest:1.00" schemaLocation="../schemas/placeOrderRequest.xsd"/>

   <import namespace="urn:company:remtp:schemas:PlaceOrderResponse:1.00" schemaLocation="../schemas/placeOrderResponse.xsd"/>

   <import namespace="urn:company:remtp:schemas:CommitOrderRequest:1.00" schemaLocation="../schemas/commitOrderRequest.xsd"/>

   <import namespace="urn:company:remtp:schemas:CommitOrderResponse:1.00" schemaLocation="../schemas/commitOrderResponse.xsd"/>

So, You need those xsd files too
