Tutorial: CICS Web Service Provider from WSDL, Top-down Method

Walks you through the steps required to create a new CICS Web service provider application starting with an existing WSDL file. The resulting Web service uses the SOAP protocol.
Restriction: This topic applies to Windows environments (local development) only.

In this tutorial, you use the top-down method to create a Web service provider that sends one or more character strings in the form of a SOAP request to a generated CICS application. The application reads and then reverses each string, and sends the reversed strings back to the Web service as a SOAP response message. To use the top-down method, you supply a WSDL file that describes the CICS application you want to access.
