Proper way of sharing reference to Application

[Vit Rozkovec]

Hi,

I'm using Quartz Scheduler for scheduling regular jobs or for keeping 
time intensive work units out from the Application's init method.

Please see Task execution. What is the right way to set application to 
the ThreadContext? Is it fine to do it like this without introducing 
leaks of any kind? Tasks may repeat forever in a few minutes interval.

Or should I code tasks in a way that does not need application set in 
thread local?

Thank you in advance.
Vit





Scheduler setup - Application's init() method
=========

JobDataMap jobDataMap = new JobDataMap();
jobDataMap.put("application", application);  <--- reference to the 
application

JobDetail job5min = newJob(Job5Min.class).withIdentity("MyIdentity", 
"group1").setJobData(jobDataMap).build();
Trigger trigger5min = newTrigger().withIdentity("trigger.5min", "group1")
.withSchedule(simpleSchedule().withIntervalInMinutes(5).repeatForever())
            .startNow().build();

scheduler.scheduleJob(job5min, trigger5min);


Task execution
=========


    public void execute(JobExecutionContext context) throws 
JobExecutionException
    {
        Application application = 
(Application)context.getMergedJobDataMap().get("application");
        ThreadContext.setApplication(application);

        ... code ...

        ThreadContext.setApplication(null);
        ThreadContext.detach();
    }



Scheduler stop - Application's onDestroy() method
=========

scheduler.stopScheduler();
