Question

I am trying to use spring batch & quartz in a project. The objective is to schedule a spring-batch job using Quartz. I have the following beans –

bean id="updateDataFeedJob"  class="package.UpdateDataFeedJob" />     

<bean id="UpdaterOnScheduleJobDetail" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
    <property name="targetObject" ref="updateDataFeedJob"/>
    <!-- the method to call inside of com.siemens.scr.schedule.UpdateDataFeedJob -->
    <property name="targetMethod" value="execute"/>
</bean> 

<bean id="cronTriggerId" class="org.springframework.scheduling.quartz.CronTriggerBean">
    <property name="jobDetail" ref="UpdaterOnScheduleJobDetail" />
    <!-- run every morning at 3AM -->
    <!--  <property name="cronExpression" value="0 0 3 * * ?" /> -->

    <!-- Fires every five minutes -->
    <property name="cronExpression" value="0 0/5 * * * ?" />
</bean>

<bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
    <property name="triggers">
        <list>
            <ref bean="cronTriggerId" />
        </list>
    </property>
</bean>

The UpdateDataFeedJob is –

public class UpdateDataFeedJob  {   
  public void execute() throws Exception {
    System.out.println("Hello World. Running the job");
    CommandLineJobRunner.main(new String[]{"GetFleetUpdatesJob.xml", "getFleetUpdatesJob"});
  }  
}

Sample Calling is –

public class Client {
    public static void main(String[] args){
        //CommandLineJobRunner.main(new String[]{"GetFleetUpdatesJob.xml", "getFleetUpdatesJob"});
        new ClassPathXmlApplicationContext("GetFleetUpdatesJob.xml");
    }   
}

I keep getting the following exception –

ERROR - Job Terminated in error: A job execution for this job is already running: JobInstance: id=0, JobParameters=[{}], Job=[getFleetUpdatesJob]
org.springframework.batch.core.repository.JobExecutionAlreadyRunningException: A job execution for this job is already running: JobInstance: id=0, JobParameters=[{}], Job=[getFleetUpdatesJob]

Answer 1

I got this working. I am not aware of the exact reason & will appreciate if someone can comment –

I added the following bean config in the applicationContext.xml

<bean id="transactionManager" class="org.springframework.batch.support.transaction.ResourcelessTransactionManager"/>

Now i dont get that exception & quartz is able to call the spring batch job
