Tutorial: CORS Service Interface

Restriction: This topic applies only when the Enterprise Server feature is enabled.

In this tutorial, you walk through the steps required to define a Web service interface using the Interface Mapping Toolkit (IMTK), deploying it to an enterprise server instance, and invoking it from a Cross Origin Resource Sharing (CORS)-supported browser via an Asynchronous Javascript and XML (AJAX) request script.

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

  1. Prerequisites
    Describes the setup and third-party software required to complete this tutorial.
  2. Demonstration Application
    Describes the BookDemo application used in this tutorial.
  3. Create a Project
    Walks you through the process of creating a Visual COBOL project for the BookDemo application and its service interface.
  4. Create a Service Interface
    Walks you through the process of creating a service interface for the BookDemo application.
  5. Define Service Interface Operations
    Walks you through the process of defining details for the ProgramCORS service interface.
  6. Create and Configure ESCORS
    Walks you through the process of creating and configuring an enterprise server instance, ESCORS, to use in this tutorial.
  7. Deploy a Service Interface
    Walks you through the steps required to build the project, set deployment properties, associate an enterprise server instance with your project, deploy the service interface, and verify the deployment results.
  8. Send an AJAX Request
    Walks you through the process of sending an AJAX request to your deployed service using a browser that supports CORS.
  9. Reconfigure and Redeploy the Service Interface
    Walks you through the process of configuring your service interface to accept AJAX requests from any origin, and redeploying the service interface to your enterprise server instance.
  10. Resend an AJAX Request
    Walks you through the process of resending an AJAX request to your deployed service running on the reconfigured ESDEMO enterprise server instance using a browser that supports CORS.
