Hi Raakhi,
JobControl is designed to be run from a new thread:
Thread t = new Thread(jobControl);
t.start();
Then you can run a loop to poll for job completion and print out status:
String oldStatus = null;
while (!jobControl.allFinished()) {
String status = getStatusString(jobControl);
if (!status.equals(oldStatus)) {
System.out.println(status);
oldStatus = status;
}
try {
Thread.sleep(1000);
} catch (InterruptedException e) {
// ignore
}
}
Hope this helps.
Tom
