logout and clear session
hi
problem: user cliks on menu with action logout...
how to clear all memory associated with his session (for ex. large beans)?
i can get session in action method:
FacesContext facesContext = FacesContext.getCurrentInstance();
SessionMap session =
(SessionMap)facesContext.getExternalContext().getSessionMap();
//session=null; - that doesnt clear session:/
and what should i do to clear memory (set null references to tell garbage
collector to whipe out objects without waiting when session expires)?
thanks for your time Men!

You need to get the actual session object from the externalContext and
call invalidate.

Hi Rico,
I saw this code sniplet in some other
cases, so I included it in my logout stuff.
Tomcat's Struts based admin app does do the same.

I guess you'll need something like:
<snip>
javax.servlet.http.HttpServletRequest request =
(javax.servlet.http.HttpServletRequest)FacesContext.getCurrentInstance().getExternalContext().getRequest();
javax.servlet.http.HttpSession session = request.getSession();
session.invalidate();
session = request.getSession(true);
</snip>
