Batch data streams are accessed from the business logic, for example, from the batch job steps
by calling BatchDataStreamMgr with jobID and stepID. JobID and stepID are retrieved from the
step bean properties list using keys BatchConstants.JOB_ID and BatchConstants.STEP_ID.
b. Map BatchConstants.JOB_ID to

    Never mind I think fixed it with this

    public String getName() {
