This sample takes you through the steps to enable an IMS™ application to call out synchronously to an external web service. You will configure a secure synchronous callout request to a secure web service that uses Security Assertions Markup Language (SAML) 2.0 unsigned tokens.
Diagrams are provided to show you the process flow and the context of the steps. The diagrams, general process flow, and detailed instructions are provided in the attached PDF file. Sample files for use to follow along the instructions are included in the attached compressed zip file.
- IMS Enterprise Suite Version 2. 2 SOAP Gateway installed on the z/OS® platform
- IMS Version 12 with integrated IMS Connect
- Application artifacts attached to this sample document
- A web server, application server, or servlet container to host the target secure web service.
This sample uses another IMS Enterprise Suite V2.2 SOAP Gateway server installed on System z® as the target web service server.
- The FEK.SFEKLOAD data set for Rational® Developer for System z. The SFEKLOAD module needs to be added to the STEPLIB in the IMS Connect startup procedure.
