Question

I have problem with cron job implemented using Quartz Scheduler. It throws NullPointerException. This problem occurs only on server so I can’t debug it. This is stacktrace:

[org.quartz.core.JobRunShell] Job myExampleJobs.simple job threw an unhandled 
Exception: 
java.lang.NullPointerException
    at com.example.schedule.JobScheduler.autowireProcessor(JobScheduler.java:269)
    at com.example.schedule.Job.execute(Job.java:17)
    at org.quartz.core.JobRunShell.run(JobRunShell.java:203)
    at org.quartz.simpl.SimpleThreadPool$WorkerThread.run(SimpleThreadPool.java:520)

JobScheduler class doesn’t have 269 lines and doesn’t have autowireProcessor method. Maybe this is method from Spring framework? I couldn’t find anything about such method.
Maybe problem concerns autowired classes in SimpleJob or in JobScheduler?

Answer 1

You have different version of the file, in the line

com.example.schedule.JobScheduler.autowireProcessor

seems like you have copy paste this code from somewhere and your accessing some example code which has a different version of the source.

Provide the more code if possible.
