i want to know it too.

in current, i use BaseMessageListener.

package com.raritan.ci.srg.scheduler;


@Component(immediate = true, property = { "cron.expression=*/5 * * * * ?" }, 
		service = RecordSyncScheduler.class)
public class RecordSyncScheduler extends BaseMessageListener {
	private static Log LOGGER = LogFactoryUtil.getLog(RecordSyncScheduler.class);
	@Override
	protected void doReceive(Message message) throws Exception {

}
	@Activate
	@Modified
	protected void activate(Map<String, Object> properties) throws SchedulerException {
		try {
			String cronExpression = GetterUtil.getString(properties.get("cron.expression"), "cronExpression");
			LOGGER.info(" cronExpression: " + cronExpression);

			String listenerClass = getClass().getName();
			Trigger jobTrigger = TriggerFactoryUtil.createTrigger(listenerClass, listenerClass, new Date(), null, cronExpression);

			SchedulerEntryImpl schedulerEntryImpl = new SchedulerEntryImpl(listenerClass, jobTrigger);
			SchedulerEngineHelperUtil.register(this, schedulerEntryImpl, DestinationNames.SCHEDULER_DISPATCH);

		} catch (Exception e) {
			LOGGER.error(e);
		}
	}

	@Deactivate
	protected void deactive() {
		SchedulerEngineHelperUtil.unregister(this);
	}
}

Hi ,

How can I create a scheduler module in liferay dxp 7.3 . Please share link to documentation or an example .

Can you create scheduler class with implements SchedulerEngine ? and then configure the cron expression?

Please pour in your inputs.
