LoginFilter.class

public class LoginFilter implements Filter {

    @Override
    public void init(FilterConfig config) throws ServletException {
        //If you have any <init-param> in web.xml, then you could get them
        //here by config.getInitParameter("name") and assign it as field.
    }

    @Override
    public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain) throws IOException, ServletException {
        System.out.println("Inside Login Filter");
        HttpServletRequest request = (HttpServletRequest) req;
        HttpServletResponse response = (HttpServletResponse) res;
        HttpSession session = request.getSession(false);
System.out.println("session..."+ session);
        if (session == null || session.getAttribute(IConstants.HAS_USER_ID) == null) {
            response.sendRedirect(request.getContextPath() + "/faces/jsp/login.jsp"); //No logged-in user found, so redirect to login page.
        } else {
            chain.doFilter(req, res); //Logged-in user found, so just continue request.
        }
    }

    @Override
    public void destroy() {
        //If you have assigned any expensive resources as field of
        //this Filter class, then you could clean/close them here.
    }

}

Setzen der session-Variablen nach erfolgreichem login

FacesContext.getCurrentInstance().getExternalContext()
                .getSessionMap()
                .put(IConstants.HAS_USER_ID, IConstants.HAS_USER_ID);

Aber das problem, das ich bin vor ist ich bekomme den unten log

Inside Login Filter
session...org.apache.catalina.session.StandardSessionFacade@1c134e1

in der Konsole und die Seite nie Weiterleitung zur nächsten Seite oder die login-Seite.
