This tutorial shows how IBM® Rational® Developer for System z can help speed efficiency of traditional mainframe, Web development and composite applications. The new capabilities help customers reduce cost and risks of rewrites by reusing and integrating core application assets with Web services and modern user interfaces.
Service-based integration is the most-common approach to exposing the business functions buried in existing systems. You can tap into the business value in your current systems by using IBM Rational Developer for System z to craft modular components from existing code written in COBOL, PL/I or Java™, and by assembling and deploying services as part of an SOA. This can also position your IT for rapid future changes to the business model. In xx minutes this scenario will show you the steps of how to wrap existing CICS/IMS programs and transactions into business components and Web services. You will then deploy and test this as CICS Web Service on System z.
Before you start
Learn what to expect from this tutorial and how to get the most out of it.
About this series
Walk through this scenario and others online as part of the Enterprise Modernization Sandbox for System z
About this tutorial
This tutorial takes you through the steps of using the Enterprise Service Tools
(EST) feature of IBM® Rational® Developer for System z™
(Version 7.1 and later) to transform an existing IBM® CICS® COBOL
program. Thereafter, you can access it as a Web service through the CICS Web
Services facilities of CICS Transaction Server for IBM® z/OS®
(Version 3 and later).
Objectives
You will learn how to generate:
- COBOL assets that can be deployed as CICS Services.
- WSDL (Web Services Description Language that describe the CICS service
created).
- Test the deployed CICS Services using the WSDL generated.
Prerequisites
Be familiar with COBOL programming.
