Calling backing bean method from HttpSessionListener

Question

Hi,
I am detecting session expiration through HttpSessionListener's sessionDestroyed() method. I have a logout() method in my backing bean which does all the session clean up. If the user clicks the logout link, then I call the logout method and do the clean up. But when the user closes the browser, then I believe that the HttpSessionListener's sessionDestroyed() method will be called. How do I call the logout() method of my backing bean from from sessionDestroyed() method of HttpSessionListener.

I did as you said, but the finalize method is never called. I can see the session timing out and sessionDestroyed() method being called, but not the finalize() method. Here is the code for sessionDestroyed()
    public void sessionDestroyed(HttpSessionEvent sessionEvent){
        System.out.println("Session Destroyed Called");
        HttpSession session = sessionEvent.getSession();
        session.invalidate();
        System.gc();
    }and for finalize()
    public void finalize() throws Throwable{
        System.out.println("In Finalize Method");
        FacesContext ctx = FacesContext.getCurrentInstance();
        Object requestObject = ctx.getApplication().getVariableResolver().
                               resolveVariable(ctx, "databaseCon");
        DatabaseCon databaseCon = (DatabaseCon) requestObject;
        Connection con = databaseCon.getConnection();
        String sql = "DELETE FROM TEMP WHERE EX_ID = ?";
        PreparedStatement pstmt = con.prepareStatement(sql);
        pstmt.setInt(1,this.getExId());
        pstmt.executeUpdate();
        super.finalize();
    }
