Xpages @PreDestroy

Question

Summary: does anyone know how to get @PreDestroy to get triggered on recycling\\ timeout of an Application Scope managed bean?

I posted a question a couple of weeks

Answer 1

There are three types of JSF listener artifacts that provide an opportunity to manually clean up objects stored in scope (including managed beans):

1. FacesContextListener: its beforeContextReleased() method is the absolute last call before any request terminates, so this is an ideal place to clean up the requestScope.
2. SessionListener: its sessionDestroyed() method provides a chance to clean up the sessionScope.
3. ApplicationListener: its applicationDestroyed() method provides a chance to clean up the applicationScope.

An ApplicationListener must be defined in an OSGi XSP Library; the first two can be defined either in a library or local to a specific NSF.

I may be wrong, but XPages is built based on JSF1.2, while Managed bean annotations are available only from JSF2.0.
