Lifecycle of Backing Beans

[Sascha Schmidt]

Hello!

I'm working on a JSF project that has some backing beans in session scope. Now we have the need to register these beans at a messaging system to exchange some data. But if the backing beans are registered at a messaging system they will never be freeed by the garbage collector. The question is: are there any lifecycle methods that are invoked when a backing bean is destroyed (end of session)? Is it possible to monito and observe backing beans?

Thank you!

Cheers,
Sascha
