How to create new JobDetail job in the run time?

I am configuring Quartz for client (NOT server) . If i need to create a new JobDetail job I would do the following

JobDetail job = JobBuilder.newJob(TestJob.class)
        .withIdentity("dummyJobName", "group1").build();

        Trigger trigger = . .  

        Scheduler scheduler = new StdSchedulerFactory().getScheduler();
        scheduler.start();
        scheduler.scheduleJob(job, trigger);

Initially I thought I would feed an object of a class to newJob.

But the newJob method takes a class as an argument (not an instance of a class). JobBuilder org.quartz.JobBuilder.newJob(Class<? extends Job> jobClass)

I can't create a new class in the run time . This is not efficient at least .

So how can I add new JobDetail job in the run time ?

Should the TestJob class be abstract so that i could customize it in the run time . I'm very confused here

There was a similar question on stackoverflow. So it appears " the Quartz scheduler's JobFactory API to load job classes through a custom class-loader and that would allow you to add jobs truly dynamically "

But how ?

Solution

You cannot directly create JobDetail out of an object unless you serialize it (which is not recommended). What you can do is you can create a HashMap and add all your data into it and do the following.

Map<String, Serializable> jobData = Maps.newHashMap();
        jobData.put("yourkey", "youdata");
        ...
JobDetail job = newJob(TestJob.class).usingJobData(jobData)
      .build();
        //build your trigger
scheduler.scheduleJob(job, trigger)
