TimerTask bean is not singleton

[FerRory]

Hello everybody,

When i start my application i start a timertask which check if all jobs are still running:

<bean id="checkifJobIsRunningTask"
		class="com.inprove.servicefarm.grid.CheckIfJobIsRunning">
		<property name="jobManager" ref="jobManager" />
		<property name="webFarmRepository" ref="webFarmRepository" />
		<property name="transactionManager" ref="transactionManager" />
	</bean>
	<bean id="checkifJobIsRunningSchedule"
		class="org.springframework.scheduling.timer.ScheduledTimerTask">
		<!-- wait 10 seconds before starting repeated execution -->
		<property name="delay" value="10000" />
		<!-- run every 10 minutes -->
		<property name="period" value="300000" />
		<property name="timerTask" ref="checkifJobIsRunningTask" />
	</bean>

On the fly jobs are added. But when checkifJobIsRunningSchedule runs it can't find jobs. But when i use the jobManager method from a webpage it works.

Can anybody help me to make my bean a singleton in a timertask?

[FerRory]

Kick, and can anybody move this topic to the Core Container forum?

[FerRory]

What have you tried? Have you tried adding additional logging or remote debugging? Are you sure the job fires? Can you post the code to CheckIfJobIsRunning?

[FerRory]

I only tried manually debugging.
the code of checkIfJobIsRunning:

package com.inprove.servicefarm.grid;

import java.util.Calendar;
import java.util.Iterator;
import java.util.List;
import java.util.TimerTask;

import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.transaction.PlatformTransactionManager;
import org.springframework.transaction.TransactionStatus;
import org.springframework.transaction.support.TransactionCallbackWithoutResult;
import org.springframework.transaction.support.TransactionTemplate;

import com.inprove.servicefarm.job.Job;
import com.inprove.servicefarm.job.JobManager;
import com.inprove.servicefarm.job.JobWebservice;
import com.inprove.servicefarm.webfarm.WebFarmRepository;
public class CheckIfJobIsRunning extends TimerTask
{
	JobManager jobManager;
	WebFarmRepository webFarmRepository;
	private TransactionTemplate transactionTemplate;

	public void run()
	{
		
		transactionTemplate.execute(new TransactionCallbackWithoutResult()
		{
			protected void doInTransactionWithoutResult(TransactionStatus status)
			{
		
				List<Job> jobs = jobManager.getRunningJobs();
				Iterator<Job> it = jobs.iterator();
				while (it.hasNext())
				{
					Job job = it.next();
					Calendar calendar = Calendar.getInstance();
					long currentTime = calendar.getTimeInMillis();
					long jobStatusTime = job.getCurrentStatusTime()
							.getTimeInMillis();
					long different = currentTime - jobStatusTime;
					long diffMinutes = different / (60 * 1000);
					if (diffMinutes > 2)
					{
						
						jobManager.stopJob(job.getId());
						webFarmRepository.addNotification(
								job.getOrganization(), job.getId(), "job",
								"Job is stopped because there wasn't contact");
					}
				}
			}
		});
	}

	public void setTransactionManager(
			PlatformTransactionManager transactionManager)
	{
		this.transactionTemplate = new TransactionTemplate(transactionManager);
	}

	public void setJobManager(JobManager jobManager)
	{
		this.jobManager = jobManager;
	}

	public void setWebFarmRepository(WebFarmRepository webFarmRepository)
	{
		this.webFarmRepository = webFarmRepository;
	}

}

But the problem is when i but a bean in the timertask the bean isn't a singleton anymore.

[wpoitras]

Are you sure the job fires?

[FerRory]

Yes i am sure. Because I can stop it with the same bean. But not when i acces the bean from CheckIfJobIsRunning

[Pitj]

Is this problem solved?
I have the same problem with TimerTask.
