Event Handler Not Working in AEM 6.4

[gauravp49120709]

******************************************************************************************************************************************************************************

Hi,

We have implemented an Event Handler registered as below:

    import org.apache.felix.scr.annotations.Component;

    import org.apache.felix.scr.annotations.Properties;

    import org.apache.felix.scr.annotations.Property;

    import org.apache.felix.scr.annotations.Reference;

    import org.apache.felix.scr.annotations.Service;

    import org.apache.sling.api.SlingConstants;

    import org.apache.sling.api.resource.ResourceResolverFactory;

    import org.apache.sling.api.resource.observation.ResourceChangeListener;

    import org.osgi.service.event.Event;

    import org.osgi.service.event.EventConstants;

    import org.osgi.service.event.EventHandler;

    import org.slf4j.Logger;

    import org.slf4j.LoggerFactory;

    /**

     * This is a node observer class which would observe the path /content/we-retail

     * for any addition or updation of nodes (type = cq:PageContent).

     * @author

     */

    @Component(label = "Test Event Listener", immediate = true, metatype =

        false, enabled = true)

    @Properties({

       /* @Property(name = EventConstants.EVENT_TOPIC, value = ReplicationAction.EVENT_TOPIC)

})*/

@Property(name = EventConstants.EVENT_TOPIC, value =

{"org/apache/sling/api/resource/Resource/ADDED",

"org/apache/sling/api/resource/Resource/CHANGED"}),

        @Property(name = EventConstants.EVENT_FILTER, value = "(&" +

"(path=/content/we-retail/us/en/*/jcr:content) (|(" + SlingConstants

.PROPERTY_CHANGED_ATTRIBUTES + "=*jcr:title) "

            + "(" + ResourceChangeListener.CHANGES + "=*jcr:title)))")

    })

    @Service(EventHandler.class)

    public class TestEventHandler implements EventHandler {

        private static final Logger LOG = LoggerFactory.getLogger(TestEventHandler.class);

        /*

         * Reference of ResourceResolverFactory object.

         */

        @Reference

        private ResourceResolverFactory resourceResolverFactory;

        /*

         * (non-Javadoc)

         * @see org.osgi.service.event.EventHandler#handleEvent(org.osgi.service.event.Event)

         */

        @Override

        public void handleEvent(Event event) {

LOG.info("Hi event is called ......");

        }

    } 

Issue is: Our handleEvent doesn't get trapped when change the property value for jcr:title on any page under the path: /content/we-retail/us/en

AEM version is: 6.4

sling version used is : org.apache.sling.api

Hi,

Can you try with JCR events.

aem63app-repo/SampleJCREvent.java at master · arunpatidar02/aem63app-repo · GitHub

OR

You are using Felix annotation, try with osgi annotations.

Hey,

I tried all above mentioned things in the Vanilla instance and found below result:

First Link: Below link didn't get work in my case, Listener didn't get invoked.

aem63app-repo/SampleJCREvent.java at master arunpatidar02/aem63app-repo GitHub

Second below link worked in my case with one exception: It is not giving the the property got changed under mentioned resource as given below screen shot.

Hi,

Try using sling Resource Change Listener.

acs-aem-samples/SampleResourceChangeListener.java at master · Adobe-Consulting-Services/acs-aem-samp...

This works on AEM 6.4. Please follow all steps in the article - including creating a system user and using the Sling Mapping Service - Creating an Event Listener for Adobe Experience Manager 6.4
