Extract from the supar good book Core JSF (thanks for advices)

p.626 How do i carry out initialization or cleanup work ?

You have several choices, depending on the timing of your tasks.

* To manage application scope objects, attache a ServletContextListener. Implement the contextInitialized and contextDestroyed methods. Add the listener class to the web.xml file like this : <listener> <listener-class>mypackage.MyListener</listener-class> </listener>

* To manage session scope objects, attach an HttpSessionListener. Implement the sessionCreated and sessionDestroyed methods. Add the listener class to the web.xml as in the preceding case

* To manage request scope objects, attach a PhaseListener. You can initialize objects in the beforePhase method when the Phase ID is APPLY_REQUEST_VALUES . You can clean up in the afterPhase method when the phase ID is RENDER_RESPONSE
