Cannot do getRequestDispatcher("/login.jsf").forward() with JSF?

[Yee CN]

Hi,   I am trying to write a very simple security filter to redirect the user to the login page if he/she is not login, something like the following:               public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain)                                     throws IOException, ServletException {                           if (!authenticated((HttpServletRequest)req)) {                                     ((HttpServletRequest)req).getRequestDispatcher(“/login.jsf”).forward(req, res);                         } else {                                     chain.doFilter(req, res);                         }             }   But I seems to be having problems with getRequestDispatcher(“/login.jsf”).forward(). The login.jsf got forwarded to OK, however the JSF engine seems to get very confused afterwards. The URL shown in the browser window is of the following form:   http://localhost:8080/myapp/login.jsf;jsessionid=46D86B99BE29C1F112F1C8BD3CBA6D6D   and nothing works till I logon via the login page directly.   Anyway around this?   Many thanks in advance.   Yee
