Hi,
I'm investigating Job Management in Junos Space. I wrote a sample of schedulable method and tried to execute it.
The sample method:
@Stateless(name = "HelloWorldEJB")
@Remote({ HelloWorld.class, JOBResultHandler.class })
public class HelloWorldImpl extends JobWorker implements HelloWorld, JOBResultHandler {
private static Logger logger = Logger.getLogger(HelloWorldImpl.class);
private static JobManager jobMgr = JxServiceLocator.lookup("cmp.JobManagerEJB");
@Schedulable
public JobInfoTO fooBar(ScheduleContext scheduleCtx) throws IOException {
InternalScheduleContext iSctx = (InternalScheduleContext) scheduleCtx;
int jobInstanceId = iSctx.getJobInstanceId(); // sets -1
// do stuff here
jobMgr.setJobInstanceResult(jobInstanceId,
"Success", JobStatus.SUCCESS, null); // throws java.lang.NullPointerException exception
return null;
}
}
Job starting method:
public String fooFooBar() {
Date scheduleTime = new Date(System.currentTimeMillis() + 30000);
ScheduleTO scheduleTo = new ScheduleTO();
scheduleTo.setStartTime(scheduleTime);
scheduleTo.setRepeatInterval("60000");
scheduleTo.setRepetitionsLeft(5);
ScheduleContext sCtx = new InternalScheduleContext();
sCtx.setSchedule(scheduleTo);
try {
fooBar(sCtx);
} catch (IOException e) {
e.printStackTrace();
}
return "Done";
}
When the job status is being set, the java.lang.NullPointerException is occurred.
Caused by: java.lang.NullPointerException
at net.juniper.jmp.cmp.jobManager.ejb.JobManagerBean.setJobInstanceResultInternal(JobManagerBean.java:1826) at net.juniper.jmp.cmp.jobManager.ejb.JobManagerBean.setJobInstanceResult(JobManagerBean.java:1787)
at net.juniper.jmp.cmp.jobManager.ejb.JobManagerBean.setJobInstanceResult(JobManagerBean.java:1776)
Also, I figured out that jobMgr.updateJobInstanceProgress() method is deprecated, but it is in Junos Space SDK documentation (Implementing Asynchronous Services (LRR)) and is represented in samples. Where could I find the updated documentation?
Is it possible to create cron tasks and cancel them using JobManager?
