    1. Configure Java Integration stage as a source.
    2. Set up column definitions.
    3. Map link index and link names.
  3. To set up the Java Integration stage as a target to pass data to Java code:
    1. Configure the Java Integration stage as a target.
    2. Set up column definitions.
    3. Map link index and link names.
  4. To set up the Java Integration stage as a transformer to transform data on input link, and write to output link:
    1. Configure the Java Integration stage as a transformer.
    2. Set up column definitions.
    3. Map link index and link names.
