try my way:
public void doFilter(ServletRequest request, ServletResponse
response,FilterChain chain) throws IOException, ServletException {
HttpServletRequest hsr = (HttpServletRequest)request;
HttpServletResponse hsr2 = (HttpServletResponse)response;
HttpSession hs = hsr.getSession();
String con = hsr.getContextPath();
String uri = hsr.getRequestURI();
int index = uri.lastIndexOf("/");
String path = uri.substring(index);
if (path.equals("/login.jsf") || path.equals("/") ||
path.equals("/sessionTimeOut.jsf")) {
chain.doFilter(request, response);
}
else{
if((hsr.getRequestedSessionId() != null
&&hsr.isRequestedSessionIdValid() == false)) {
String queryString = hsr.getQueryString();
String page=con+"/sessionTimeOut.jsf";
hsr2.sendRedirect(page + (queryString == null ? "" :
"?" + queryString));
}
else {
chain.doFilter(request, response);
}
}
}
