Using Bean to forward page.

Question

Hey I just was wondering if there is a way to directly forward a page from the bean using "Facescontext" or something from the bean to another page? I need this for session timing out. So I have code that runs a function as soon as the session expires but i want the page to move to the login page.. any suggestions?

For that purpose, you need to use Filter,
public class LogoutFilter implements Filter
    //the login page uri
    private static final String SIGNOUT_PAGE_URI = "logOut.jsf";
    public void init( FilterConfig filterConfig ) throws ServletException
    public void doFilter( ServletRequest req, ServletResponse res, FilterChain chain ) throws IOException, ServletException
        HttpServletRequest request = (HttpServletRequest )req;
        String url = request.getServletPath();
        String query = request.getQueryString();
        if( !authorize(request) && !isRedirected(request))
            request.getRequestDispatcher( SIGNOUT_PAGE_URI ).forward( req, res );
        else
            chain.doFilter( req, res );
    public void destroy()
    private boolean authorize( HttpServletRequest req )
        Object obj = req.getSession().getAttribute( UserBean.KEY_CURRENT_USER );
        return obj != null;
    private boolean isRedirected( HttpServletRequest req )
         boolean isRedirected = false;
        Object obj = req.getParameter(AppConstants.SecurityConstants.IS_REDIRECTED);
        boolean isObjectNull = (obj == null);
        if(!isObjectNull){
             String objectValue = (String)obj;
             isRedirected = objectValue.equals(Boolean.TRUE.toString());
        return  (isRedirected);
Register this filter in web.xml:
<filter>
  <filter-name>logoutFilter</filter-name>
  <filter-class>someOrg.filter.LogoutFilter</filter-class>
</filter>
<filter-mapping>
  <filter-name>logoutFilter</filter-name>
  <url-pattern>/faces/*</url-pattern>
</filter-mapping>
