Scheduler Job throwing exceptions

[arindam6600]

I tried writing a scheduler job using the Job class but somehow it won't execute. It keeps throwing null as an exception. This is what I'm getting in logs :

This is the code that I've written :

package com.mysite.core.schedulers;

import java.io.Serializable;
import java.util.HashMap;
import java.util.Map;

import org.apache.sling.commons.scheduler.Job;
import org.apache.sling.commons.scheduler.JobContext;
import org.apache.sling.commons.scheduler.ScheduleOptions;
import org.apache.sling.commons.scheduler.Scheduler;
import org.osgi.service.component.annotations.Activate;
import org.osgi.service.component.annotations.Component;
import org.osgi.service.component.annotations.Deactivate;
import org.osgi.service.component.annotations.Reference;
import org.osgi.service.metatype.annotations.Designate;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

@Component(immediate = true, service = Job.class)
@Designate(ocd = SchedulerConfigThree.class)

public class PracticeSchedulerDayThree implements Job {
	private static final Logger LOG = LoggerFactory.getLogger(PracticeSchedulerDayThree.class);
	
	private int schedulerId;
	
	@Reference
	private Scheduler scheduler;
	
	@Activate
	protected void activate(SchedulerConfigThree configThree) {
		schedulerId = configThree.schedulerDayThreeName().hashCode();
		
		ScheduleOptions in = scheduler.EXPR("0 56 23 1/1 * ? *");
		Map<String, Serializable> inMap = new HashMap<>();
		inMap.put("country", "India");
		inMap.put("URL", "www.india.com");
		scheduler.schedule(this, in);
		
		ScheduleOptions de = scheduler.EXPR("0 59 23 1/1 * ? *");
		Map<String, Serializable> deMap = new HashMap<>();
		deMap.put("country", "Denmark");
		deMap.put("URL", "www.de.com");
		scheduler.schedule(this, de);
	}
	
	@Deactivate
	protected void deactivate() {
		scheduler.unschedule(String.valueOf(schedulerId));
	}

	@Override
	public void execute(JobContext jobContext) {
		LOG.info("\n ===> COUNTRY : URL {} : {}", jobContext.getConfiguration().get("country"), jobContext.getConfiguration().get("URL"));
	}

}

Can someone please let me know what am I doing wrong over here?

[DPrakashRaj · Accepted solution]

It seems you forget to put the map config inside scheduleOptions object.

so basically you should be doing this one in.config(inMap) and de.config(deMap) before calling scheduler.schedule() in your class.

Thank you @DPrakashRaj . Yes, I missed out that step. Thanks once again
