Subject RE: ADFFACES-37 (PPR and timeout)
Date Fri, 30 Mar 2007 20:21:18 GMT
Thank you, but this isn't sufficient by itself. I'm using Acegi for
security, which uses a filter to authenticate before my app receives
control. Therefore, by the time the phase listener can execute, Acegi
has already created a new user object for me, so I can't detect the
timeout.

I have a servlet filter in place to do a redirect to a 'home' page in
case of timeout. That works, but PPR requests still do not. This
listener seems like the right idea though. I want to fire an arbitrary
navigation rule when a timeout is detected. I simply cannot detect it by
checking for the non-existence of a user object. I also tried having it
check for the presence of an invalid session id in the request (what my
servlet filter does), but Acegi apparently also fixes that too.

Ideas?

Daniel,

Here is a solution to your problem. This will redirect the client back
to your login page event when it is a PPR.

In faces-config.xml:

   <lifecycle>

 
<phase-listener>org.nemours.estore.ui.filter.LoginPhaseListener</phase-l
istener>

    </lifecycle>

In LoginPhaseListener:

public class LoginPhaseListener implements PhaseListener {

    /**
     * @see
javax.faces.event.PhaseListener#afterPhase(javax.faces.event.PhaseEvent)
     */
    public void afterPhase(PhaseEvent pPhaseEvent) {
        log.debug("afterPhase:" + pPhaseEvent.getPhaseId());
    }

    /**
     * @see
javax.faces.event.PhaseListener#beforePhase(javax.faces.event.PhaseEvent
)
     */
    public void beforePhase(PhaseEvent pPhaseEvent) {
        log.debug("beforePhase:" + pPhaseEvent.getPhaseId());
        if (pPhaseEvent.getPhaseId() == PhaseId.RENDER_RESPONSE) {
            FacesContext facesContext = pPhaseEvent.getFacesContext();
            log.debug("source:" + pPhaseEvent.getSource().toString());

            HttpSession httpSession = (HttpSession)
facesContext.getExternalContext().getSession(false);
            String requestURI =
((HttpServletRequest)facesContext.getExternalContext().getRequest()).get
RequestURI();
            if ((!requestURI.endsWith("login.jsf")) &&
(requestURI.endsWith(".jsf"))) {
                AppUser user = (AppUser)
httpSession.getAttribute(LOOKUP_SESSION_USER);
                if ((user == null) || (user.equals(""))) {
 
facesContext.getApplication().getNavigationHandler().handleNavigation(fa
cesContext, "loginAction",
                            "failure");
                }
            }
        }
    }

    /**
     * @see javax.faces.event.PhaseListener#getPhaseId()
     */
    public PhaseId getPhaseId() {
        return PhaseId.ANY_PHASE;
    }
}

Hi,

 

I'm curious if any more thought has gone into the timeout issue with PPR
(ADFFACES-37). It's still a problem. If the session times out and and
PPR request is (I believe) sent to the login page. But the browser
doesn't display it and the user has no way of knowing. They just get a
page that doesn't update.

 

Are there workarounds?

 

Thanks.

Dan
