Scenario: "I have a COBOL server program and want to call this from a REST client."

Solution: Take an existing COBOL server program and generate the integration logic to call it from a REST client .

The COBOL server can reside in different operating systems and environments.

Choose a scenario for information on

• alternative architectures (if applicable)

• installation requirements

• development steps

Continue with the appropriate scenario:

• z/OS - Choose your z/OS environment:

  • CICS - Choose your CICS calling convention:

    • Channel Container using
