Subject: Re: Faces context is nullThanks for your reply guys.I also tried to use request.getRequestDispatcher("./login.jsf").forward(request, response) instruction to forward to the login page incase of authentication failure. But when this instruction gets executed instead of loading the login page, the first page of the website (only accessible to logged in users) is shown, which is strange. I added system println statements to my code. When login.jsf is loaded for the first time the output appears, but later when i am forwarding to it after login failure it isnt.Any idea of what might be the problem.once again thanks for your repliesHassnain

Right!

FacesContext is setup inside of FacesServlet.service() ([1]) for each request.
So your filter is called before service() is call. That's why you get
a null value.

J2EE based security might be usful. Or ou may try a PhaseListener
instead, which is called *inside* the Faces framework.
