Vamos começar do começo então… Colocando um breakpoint vc consegue chegar a sua classe de filtro?

Segue a classe filtro: 
public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
        HttpServletRequest rq = (HttpServletRequest) request;
        HttpServletResponse rp = (HttpServletResponse) response;
        boolean auth = rq.getSession().getAttribute("user") != null;

        if (!auth && !rq.getRequestURL().toString().contains("login.faces")) {
            rp.sendRedirect(rq.getContextPath() + "/login.faces");
        }else {
            try {
                chain.doFilter(request, response);
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
    }

Bem, já que o filtro está funcionando, ele vai executando até qual linha? onde ele dá o erro?

fernandosc

O erro está acontecendo neste linha:

chain.doFilter(request, response);
