JSF redirect a logged out user

[malik ge]

Hi,
I am following this post http://aquaryus.wordpress.com/2012/03/29/jsf-login-logout-methods-session-timeouts-page-jumping-issues-facelets/
to redirect user to "login.xhtml" if the user is not logged in.
So far I have 4 pages

index.xhtml

register.xhtml

login.xhtml

welcome.xhtml

If user tries to go to welcome page, without authentication, he shall be redirected to login page,
but when I run the application, only login.xhtml page is accessible without authentication.
After logging in all the pages are accessible.
I want only welcome.xhtml page to be accessed after authentication.

My Code:

public class AuthorizationListener implements PhaseListener
{
    @Override
    public void afterPhase(PhaseEvent event)
    {
        FacesContext facesContext = event.getFacesContext();
        
        HttpSession session = (HttpSession) facesContext.getExternalContext().getSession(false);

        if(session==null)
        {
            NavigationHandler nh = facesContext.getApplication().getNavigationHandler();
            nh.handleNavigation(facesContext, null, "login");
        }
        else 
        {
            Object currentUser = session.getAttribute("userName");

            if ((currentUser == null || currentUser == ""))
            {
                NavigationHandler nh = facesContext.getApplication().getNavigationHandler();
                nh.handleNavigation(facesContext, null, "login");
            }            
        }
    }

    @Override
    public void beforePhase(PhaseEvent event)
    {

    }

    @Override
    public PhaseId getPhaseId()
    {
        return PhaseId.RESTORE_VIEW;
    }
}

Thanks

It looks like you have to "deauthorize" register and login? but why?
Simply check if the user is logged in via some filter and redirect them back to where they came from.

I am creating small application for testing.
The reason for "deauthorizing" register.xhtml page is that, first the user can register themselves, then they can login.

Simply check if the user is logged in via some filter and redirect them back to where they came from.

Can you please explain a little more how can I do that?

One of the reasons why I recommend using the J2EE standard security system is because you don't have to do convoluted things like this when you use it. Although the main reason is because, as I've said too many times, it's because I've never run into a user-designed security system that was actually secure. And in your specific case, ANY request from a logger-out user to a secured URL would automatically redirect to a login without a single line of Java code required.

I would not use JSF for this kind of task, in any event. It would at best only be secure in cases where each and every submitted URL with security implications was a JSF URL, and that's rarely the case for me. Requests to servlets to create reports, requests to JSPs to create XML files, stuff like that would not go through JSF and therefore would not go through a phase listener. A servletlistener is a better place to put stuff like this.
