Hello everyone, 

I m trying to use scheduler and javamail in liferay to send mail on specific date. The mail part is working great but i m facing some issues with the quartz Scheduler system. I m actually creating a trigger and starting a job at specific time, then i get my data from Message in the do receive and send a mail. I first got an error with deserialization of my MailMessage Type, this error showed up on the exact time of the job triggering date. After adding

 json.deserialization.whitelist.class.names=javax.mail.internet.InternetAddress,com.liferay.mail.kernel.model.MailMessage,com.liferay.portal.kernel.messaging.Message 

in my port-ext.properties the error disapeared but my doReceive seem to not work now. in the database, the job entry is disapearing at the triggering time. I don't have any error or log showing up. Here is my code : 

Listener : 

@Component(
          immediate = true, property = {"cron.expression=0 0 0 * * ?"},
          service = MailSchedulerImpl.class
        )
        public class MailSchedulerImpl extends BaseMessageListener {

          /**
           * doReceive: This is where the magic happens, this is where you want to do the work for
           * the scheduled job.
           * @param message This is the message object tied to the job.  If you stored data with the
           *                job, the message will contain that data.   
           * @throws Exception In case there is some sort of error processing the task.
           */
          @Override
          protected void doReceive(Message message) throws Exception {
             System.out.println("Je passe bien ici ");
             MailMessage m = (MailMessage) message.get("mail");
             MailServiceUtil.sendEmail(m);
            _log.info("Scheduled task executed...");
          }

Trigger creation : 

        Calendar mCal = Calendar.getInstance();
        Date dateEnvoie = newsletter.getDateEnvoie();
        mCal.setTime(dateEnvoie);
        System.out.println(dateEnvoie);      

String jobCronPattern = SchedulerEngineHelperUtil.getCronText(mCal, false);
        ServiceContext actionRequest = ServiceContextThreadLocal.getServiceContext();
        System.out.println(jobCronPattern);
        ThemeDisplay themeDisplay = (ThemeDisplay) actionRequest.getAttribute(WebKeys.THEME_DISPLAY);
        Trigger trigger = TriggerFactoryUtil.createTrigger(MailSchedulerImpl.class.getName(), "mail_"+newsletter.getNewsletterId(), jobCronPattern);
        Message message = new Message();
        message.put("mail", mailMessage);
        message.put(SchedulerEngine.JOB_NAME,MailSchedulerImpl.class.getName());
        message.setDestinationName(DestinationNames.SCHEDULER_DISPATCH);
        SchedulerEngineHelperUtil.schedule(trigger,  StorageType.PERSISTED, trigger.getJobName() + newsletter.getNewsletterId(),  DestinationNames.SCHEDULER_DISPATCH, message, 5);
        SchedulerEngineHelperUtil.start();
