IMS Solutions: Utilizing the IMS Synchronous Callout Function to Invoke a CICS Web Service Through IMS SOAP Gateway

This white paper uses a sample scenario to demonstrate how to use the synchronous callout function of IMS to invoke an existing CICS Web service through the IMS SOAP Gateway. The scenario takes an existing IMS application written in COBOL and enhances it to request additional information from an existing CICS Web service. The white paper provides an overview of the sample configuration, code samples, and step-by-step instructions on how to generate necessary artifacts. The white paper also provides information on how to troubleshoot problems one may encounter while recreating the scenario. This white paper describes how to implement synchronous callout in an IMS application to invoke an existing CICS Web service through the IMS SOAP Gateway.
