Hi
I use data queue, and CL to submit Java job in Batch
(used a different subsystem then QBATCH , since in oue
machine QBATCH will allow ro run only one job in
bacth)
I use CL command as below to submit the job in batch
is not already active
SBMJOB CMD(QSH CMD(MyClass)) JOB(JobName) +
JOBQ(MAPSSBSQ) OUTQ(MAPSSBSOUT)
In MyClass I have the logic given below which listents
to a data queue and as soon it gets any data takes the
data and process the request(in my case create pdf
file on IFS file system of AS400)
hope this helps
