Option 1: XWiki is a java app so all you can write some java class with a shutdown hook, something like Runtime.getRuntime().addShutdownHook. Then you package your class in a jar and drop it in WEB-INF/lib. Option 2: You write an XWiki component and implement the Disposable interface. See http://extensions.xwiki.org/xwiki/bin/view/Extension/Component+Module#HComp… Thanks -Vincent

Thanks, Edward.

This only works if your component is initialized before the shutdown so you will need a component which is always initialized like event listeners. Option 3: Implement an event listener component listening to org.xwiki.observation.event.ApplicationStoppedEvent event.

Thanks, Edward.

Thank you for rapid reply! Trying to implement it using addShutdownHook to keep it as simple as possible. Edward. On Wed, Aug 24, 2016 at 3:20 PM Thomas Mortagne <thomas.mortagne(a)xwiki.com> wrote:
