WebFilter using omnifaces getting a 404 and not working

Question

I´m using omnifaces and prmifaces to make a login and trying to implement a webFilter from omnifaces. But i always get a 404 and nothing is happenning. Can someone please help me! This is my web.xml.

    <?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.1" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd">

        <param-name>javax.faces.PROJECT_STAGE</param-name>
        <param-value>Production</param-value>
    </context-param>
    <context-param>

    </context-param>
    <filter>
        <filter-name>loginFilter</filter-name>
        <filter-class>pt.isec.pd.pgs.login.LoginFilter</filter-class>
    </filter>
    <servlet>
        <servlet-name>Faces Servlet</servlet-name>
        <servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>Faces Servlet</servlet-name>
        <url-pattern>/*</url-pattern>
    </servlet-mapping>
    <welcome-file-list>
        <welcome-file>login.xhtml</welcome-file>
    </welcome-file-list>
</web-app>

and this is my LoginFilter class.

@WebFilter("/secured/*")
public class LoginFilter extends HttpFilter {

    @Inject
    private LoginBackingBean loginBackingBean;

    @Override
    public void init(FilterConfig filterConfig) throws ServletException {
    }

    @Override
    public void destroy() {
    }

    @Override
    public void doFilter(HttpServletRequest request, HttpServletResponse response, HttpSession session, FilterChain chain) throws ServletException, IOException {
        System.out.println("doFilter");
        String loginURL = request.getContextPath() + "/login.xhtml";

        boolean loggedIn = (session != null) && (session.getAttribute("user") != null);
        boolean loginRequest = request.getRequestURI().equals(loginURL);
        boolean resourceRequest = Servlets.isFacesResourceRequest(request);

        if (loggedIn || loginRequest || resourceRequest) {
            if (!resourceRequest) { // Prevent browser from caching restricted resources. See also https://stackoverflow.com/q/4194207/157882
                Servlets.setNoCacheHeaders(response);
            }

            chain.doFilter(request, response); // So, just continue request.
        } else {
            Servlets.facesRedirect(request, response, loginURL);
        }
    }
}

i have a /login.xhtml and a /secured/home.xhtml. my backingBean is LoginBackingBean.

What am i doing wrong!? If someone need any more info, please let me know. Because i´m quite frustrating. Thanx you in advance.

Change my approach to a "default" java LoginFilter. And it solved my problema. this is my filter class

@WebFilter("/secured/*")
public class LoginFilter implements Filter {

final static Logger LOGGER = Logger.getLogger(LoginFilter.class);

 @Inject
 private LoginBackingBean loginBean;

@Override
public void init(FilterConfig filterConfig) throws ServletException {
LOGGER.debug("init()");}

@Override
public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {

LOGGER.debug("doFilter() -> LoggedIn: " + loginBean.isLoggedIn());
    if (loginBean == null || !loginBean.isLoggedIn()) {
        LOGGER.debug("to login!");
        String contextPath = ((HttpServletRequest) request).getContextPath();
        ((HttpServletResponse) response).sendRedirect(contextPath + "/login.xhtml");
    }
    chain.doFilter(request, response);
}

@Override
public void destroy() {
    LOGGER.debug("destroy()");
   }
}

This is my web.xml
