Using object-oriented COBOL and Java under IMS

You can mix object-oriented COBOL and Java™ in an application that runs in a Java dependent region.

For example, you can:
  • Call a COBOL method from a Java application. You can build the messaging portion of your application in Java and call COBOL methods to access IMS databases.
  • Build a mixed COBOL and Java application that starts with the main method of a COBOL class and that invokes Java routines.

You must run these applications in either a Java message processing (JMP) dependent region or a Java batch processing (JBP) dependent region. A program that reads from the message queue (regardless of the language) must run in a JMP dependent region.
