Destroy JSF Bean on Session Timeout

[puneet.bansal]

I am using JBoss 4.0.5 and Apache myfaces 1.1. I have set session
timeout in my web.xml. But I read somewhere that specifying the
session timeout in web.xml does not clear jsf managed beans (session
scope) from the server memory. Is this true? If yes, then how can I
clear out the JSF beans from the server memory on session timeout?

Thanks.
