Tutorial: REST Web Service

Walks you through the process of defining a Representational State Transfer (REST) Web service using the Interface Mapping Toolkit (IMTK), deploying it to an enterprise server instance, and generating and running a client to access it.
Restriction: This topic applies to Windows environments (local development) only.

Before You Begin

Before beginning this tutorial, be sure that you have completed all tasks outlined in the Prerequisites section of the Tutorials: Interface Mapping Toolkit topic.

Overview

In this tutorial, you work through the following tasks:

  • Review the code in the COBOL demonstration application to become familiar with how it works
  • Create, configure, and populate an Eclipse project.
  • Using the Interface Mapping Toolkit (IMTK), define a SOAP Web Service to access the COBOL application
  • Create and configure an enterprise server instance on which to run the SOAP Web service.
  • Deploy the Web service to the enterprise server
  • Generate a COBOL client to access the Web service
  • Run the COBOL client to debug the Web service

Sequence

Complete this tutorial by following the instructions in the following topics in the order listed here. The bottom of each topic provides Previous topic and Next topic navigational links to help you proceed through the tutorial in its proper sequence:
