You can develop a custom replication event handler for Adobe Experience Manager (AEM) that is invoked when AEM content is activated. For example, a custom replication event handler can track details when an AEM web page is activated, as shown in this illustration.

To create an AEM replication event handler, you create an OSGi bundle that contains a class that implements org.osgi.service.event.EventHandler. For information, seeEventHandler.
