Meet-in-middle: Generating artifacts with the WSDL file and IMS callout application

Use IBM® Rational® Developer for System z® to generate the correlator file and the XML converter that are needed to enable your IMS application to run as a web service consumer.

For Rational Developer for System z to perform data mapping and create the mapping session files between your IMS applications and the web service you are accessing, you must have the web service WSDL file and the file that contains the data structures describing the interface to your application on your workstation.

To generate web services artifact files:
  1. Create a project in the z/OS® Project perspective with your project source files in the z/OS project perspective.
  2. Generate the request data mapping session file.
  3. Generate the response data mapping session file.
  4. Generate the web services files.
The artifacts generated are:
  • The correlator file (.xml)
  • The XML converters (.cbl)
  • Optionally, the input and output data mapping XSD files (.xsd)
