SUMMARY
This article describes how to integrate a .NET client with an Apache SOAP 2.2-based Web service. This article assumes that a Web Services Description Language (WSDL) file exists and was created by using the IBM Web Services Toolkit.

Requirements
This article assumes that you are familiar with the following topics:
Reading and editing WSDL files
Microsoft .NET Framework Software Development Kit (SDK)

Prepare the WSDL File for .NET
The IBM Web Services Toolkit places the WSDL information in two files:
Java class name _Service.wsdl (the service file)
Java class name _Service-interface.wsdl (the interface file)
The first file contains the service information. The second file contains the message, port type, and binding definitions. Because of incompatibilities between IBM-generated WSDL and the Microsoft .NET WSDL implementation, you must edit the files that the IBM Web Services Toolkit generates so that the .NET environment can read them in.

NOTE : The .NET environment can handle WSDL imports. However, the WSDL that the IBM Web Services Toolkit generates improperly uses the targetNamespace attribute and incorrectly references other internal elements (specifically, the <binding>, <message>, and <portType> elements). The easiest and quickest approach is to merge and edit the files as follows:
Copy both .wsdl files to your computer.


Open the service file, and delete the <import> element.


Open the interface file, and copy all of the elements except for the <definitions> tags. Paste these elements into the service file above the <service> element.


In the <portType> element, append the "tns:" string to the message attribute values on the <input> and <output> child elements.


In the <binding> element, append the "tns:" string to the type attribute value.


In the <service> element, append the "tns:" string to the binding and name attribute values on the <port> child element.


For the root-level <definitions> element, set xmlns:xsd namespace to reference http://www.w3.org/2001/XMLSchema URI (that is, change "1999" to "2001").

Create the Proxy
To create the proxy, you can use either of the following methods:
Use the Wsdl.exe tool, and include the file in a project.
Create a Web reference from within the Microsoft Visual Studio .NET Integrated Development Environment (IDE).
After you create the proxy, you can use the proxy as you would any other Microsoft .NET class.
