title: java quartz get all details from a scheduled job
body: <p>I have a Scheduler with number of jobs. I want to be able to show all of the active jobs that are in the scheduler, by that I mean that i want to show when each job is triggerd. 
  This is my code:</p>
  
  <pre><code>        sched.start();                
  
          JobDetail job = newJob(Jobs.class)
          .withIdentity(job_name_, "default") 
          .usingJobData("job_type", job_type_)            
          .build();
  
           Trigger trigger = newTrigger()
          .withIdentity(job_name_, "default")
          .startNow()                
          .withSchedule(cronSchedule(date_time_)) 
          .build();
  
          sched.scheduleJob(job, trigger);      
  </code></pre>
  
  <p>How can this be done? how do i get the cron expression from the trigger of the job ? also is there a way to see the cron expression as a date or somthing more detailed then the expression itself?</p>
  
  <p>Any help will be appritiated,</p>
  
  <p>Thank's In Advance.</p>
