Getting the session inside a event

pmbroca_ — Fri, 03 Apr 2015 10:19:47 GMT

Hello! I have implemented a scheduler associated with an event. I would like to search documents inside it with the session. Unfortunately when I try to get the session from the event it returns null. There's the code of my scheduler:

 <?xml version="1.0"?>
<component name="fr.sword.bdf.arche.distribution.core.schedule">
	<extension target="org.nuxeo.ecm.core.scheduler.SchedulerService"
		point="schedule">
		<schedule id="embargoSchedule">
			<eventId>EmbargoEvent</eventId>
			<eventCategory>default</eventCategory>
			<!-- Every 2 minutes -->
			<cronExpression>0 0/2 * 1/1 * ? *</cronExpression>
		</schedule>
	</extension>
</component>

The code of my event contrib:

<?xml version="1.0"?>
<component name="fr.sword.bdf.arche.distribution.core.event">

	<extension target="org.nuxeo.ecm.core.event.EventServiceComponent"
		point="listener">

		<listener name="EmbargoEvent" async="false" postCommit="true"
			priority="140" class="fr.sword.bdf.arche.distribution.core.event.EmbargoEvent">
			<event>EmbargoEvent</event>
		</listener>

	</extension>

</component>

And the code of the event listener:

public class EmbargoEvent implements EventListener {

	private static final Log LOG = LogFactory.getLog(EmbargoEvent.class);

	public static final String EVENT_NAME = "EmbargoEvent";

	protected Lock lock = new ReentrantLock();

	@Override
	public void handleEvent(Event event) throws ClientException {
		if (event != null && EVENT_NAME.equals(event.getName())) {
			final EventContext context = event.getContext();
			final CoreSession session = context.getCoreSession();
			List<DocumentModel> docs = getDocListEmbargo(session, event);
			LOG.error("Size docs: " + docs.size());
		}
	}

	public static List<DocumentModel> getDocListEmbargo(CoreSession session, Event event) throws ClientException {
		try {
			List<DocumentModel> results = new ArrayList<DocumentModel>();

			// Requête de récupération des documents statut
			final StringBuilder query = new StringBuilder("SELECT * FROM ");
			query.append(DocumentConstants.DOCUMENT_EXTERNE_DOC_TYPE);
			query.append(" WHERE ");
			query.append(DocumentConstants.DOCUMENT_EXTERNE_SCHEMA_PREFIX);
			query.append(" AND ");
			query.append("ecm:isProxy = 0 ");
			query.append(" AND ");
			query.append("ecm:currentLifeCycleState != 'deleted' ");
			query.append(" AND ");
			query.append("(dext:niveauConfidentialite = 2 OR dext:niveauConfidentialite = 3) ");

			final DocumentModelList docs = session.query(query.toString());

			for (int i = 0; i < docs.size(); i++) {
				results.add(docs.get(i));
			}

			return results;
		} catch (Exception e) {
			event.markRollBack(null, e);
			throw new ClientException(e);
		}
	}
}

Thank you in advance.

Forget about it I found the solution thanks to this link: https://github.com/easysoa/EasySOA/wiki/Nuxeo-CoreSession-and-Transactions

just need a help...just need to know if you have created the scheduler as a nuxeo component and the listener as a document listener?
