Tutorial: CICS Web Service Provider from JSON, Request-Response Top-down Method

Walks you through the steps required to create a new CICS Web service provider application from a set of request and response JSON files.

In this tutorial, you use the top-down method to create a CICS Web service provider application that receives a character string in the form of a JSON request. The application reverses the string, and sends the reversed string back to the requester as a JSON response message.

To use the top-down method to create a CICS Web service provider, you start with request and response JSON that describes request and response data structures. From the JSON, you generate a skeleton CICS COBOL provider application, and a WSBIND file that provides mapping between the JSON and the COBOL data structures.

The sample project used in this tutorial to create your Enterprise Developer for Eclipse project contains the reverse.json schema, which describes both the request and response data structures.
