What is the better way to stop currently running job in quartz scheduler? - quartz-scheduler

Question

I am using quartz Scheduler .I want to stop currently running job.
I am using this one in a web application .When I click on start button then job execution is started but when I want to stop this executing job using stop button .
But I am not able to stop.
Please give me an idea how can I stop currently running job?
I am giving my code.
//when i click on start button then this class will call.
#WebServlet("/ScheduleController")
public class AscentScheduleController extends HttpServlet {
private static final long serialVersionUID = 1L;
private static final String RANDOM = "random";
Scheduler schedulerRecon;
Scheduler schedulerPos;
Scheduler schedulerFile;
Scheduler schedulerEtl;
Trigger triggerIris;
JobKey jobKey;
JobDetail job;
String key;
int time;
/**
* #see HttpServlet#HttpServlet()
*/
public AscentScheduleController() {
super();
}
protected void doGet(HttpServletRequest request,HttpServletResponse response) throws ServletException, IOException {
Connection con = null;
PreparedStatement ps = null;
ResultSet rs = null;
HttpSession session = request.getSession();
try {
String id = request.getParameter("id");
System.out.println("hello in controller");
System.out.println(id);
System.out.println(Thread.currentThread().getName());
schedulerRecon = new StdSchedulerFactory()
.getScheduler();
schedulerRecon.start();
session.setAttribute(id,schedulerRecon );
System.out.println();// SimpleScheduleBuilder.simpleSchedule().withIntervalInSeconds(10).repeatForever()).build();
System.out.println();
System.out.println();
System.out.println("controller schedil "+schedulerRecon);
System.out.println(Thread.currentThread().getName());
jobKey = new JobKey("jobKeyIris", "group1");
job = JobBuilder.newJob(DemoTrgger.class).withIdentity("jobKey").build();
triggerIris = TriggerBuilder.newTrigger().withIdentity("triggerIris", "group1").startNow()
.withSchedule(SimpleScheduleBuilder.simpleSchedule().withIntervalInSeconds(60).// repeatForever()).build();
withRepeatCount(0)).build();
session.setAttribute("job", jobKey);
System.out.println();// SimpleScheduleBuilder.simpleSchedule().withIntervalInSeconds(10).repeatForever()).build();
System.out.println();
System.out.println();
System.out.println("controller job key "+jobKey);
// temp=temp+temp;
schedulerRecon.scheduleJob(job, triggerIris);
// scheduler.scheduleJob(jobQCB, triggerQCB);
System.out.println("fire job");
}
}
//and my job class which implement Job is below
public class DemoTrgger implements Job {
public static Thread th;
#Override
public void execute(JobExecutionContext arg0) throws JobExecutionException {
System.out.println();
System.out.println("demo trigger "+Thread.currentThread().getName()+"thread obj "+Thread.currentThread());
th = Thread.currentThread();
System.out.println();
for(long i=0l;i<2000000;i++){
System.out.println("i--------- "+i);
}
for(long i=0l;i<2000000l;i++){
System.out.println("j--- "+i);
}
}
}
when I click on stop button the below class will call.Here I get the Scheduler reference which I use in start using session and I want stop respectively running job.
#WebServlet("/SchedulerStopController")
public class SchedulerStopController extends HttpServlet implements InterruptableJob {
private static final long serialVersionUID = 1L;
/**
* #see HttpServlet#HttpServlet()
*/
public SchedulerStopController() {
super();
// TODO Auto-generated constructor stub
}
/**
* #see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse response)
*/
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
// TODO Auto-generated method stub
String id=request.getParameter("id");
System.out.println(id);
HttpSession session=request.getSession();
Scheduler schedular=(Scheduler) session.getAttribute(id);
System.out.println();// SimpleScheduleBuilder.simpleSchedule().withIntervalInSeconds(10).repeatForever()).build();
System.out.println();
System.out.println();
System.out.println("stop schedular "+schedular);
try {
SchedulerMetaData metaData = schedular.getMetaData();
} catch (SchedulerException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
// log.info("Executed " + metaData.getNumberOfJobsExecuted() + " jobs.");
/*Runtime.getRuntime().addShutdownHook(new Thread()
{
public void run()
{
System.out.println(Thread.currentThread().getName());
// this will get called on shutdown
// TODO Auto-generated catch block
e.printStackTrace();
}
System.out.println("------- My own shutdown hook -----------------");
}
});
*/
try {
JobKey jobKey=(JobKey) session.getAttribute("job");
System.out.println();// SimpleScheduleBuilder.simpleSchedule().withIntervalInSeconds(10).repeatForever()).build();
System.out.println();
System.out.println("stop controller "+Thread.currentThread().getName());
System.out.println();
System.out.println("stop job "+jobKey);
schedular.deleteJob(jobKey);
} catch (SchedulerException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
thanks.
