I don't redirect or forward my user to another page. So when the my SessionExpiredExceptionHandler
(extends ExceptionHandlerWrapper
) handles the ViewExireException. I want the user to stay on the same page and display a PrimeFaces Dialog. For notifying that the session has expired and that the user needs to login again (dialog based). I am use Servlet 3.1 functions to login/logout user and Basic/file
for auth-method to map the users to different system roles.
What is happening now is that the View/page get refreshed after 2 min, but the session doesn't get invalidated. That only happens the second time when the page refreshes, after 4 min.
<session-config>
<session-timeout>2</session-timeout>
</session-config>
Edit: Which is refreshed by the meta tag:
<meta http-equiv="refresh" content="#{session.maxInactiveInterval}" />
How can I make SessionExpiredExceptionHandler
invalidate the session object (Servlet logout) when the Exceptions occur the first time, and how can I invoke a JavaScript (expireDlg.show()) on the client to display a PrimeFaces dialog ?
I have looked at some other threads but not found a viable solution. Session time-out
SessionExpiredExceptionHandler
@Override
public void handle() throws FacesException {
for (Iterator<ExceptionQueuedEvent> i = getUnhandledExceptionQueuedEvents().iterator(); i.hasNext();) {
ExceptionQueuedEvent event = i.next();
ExceptionQueuedEventContext context = (ExceptionQueuedEventContext) event.getSource();
Throwable t = context.getException();
if (t instanceof ViewExpiredException) {
ViewExpiredException vee = (ViewExpiredException) t;
FacesContext fc = FacesContext.getCurrentInstance();
Map<String, Object> requestMap = fc.getExternalContext().getRequestMap();
NavigationHandler nav = fc.getApplication().getNavigationHandler();
try {
requestMap.put("currentViewId", vee.getViewId());
nav.handleNavigation(fc, null, "Home");
fc.renderResponse();
} finally {
i.remove();
}
}
}
// At this point, the queue will not contain any ViewExpiredEvents.
// Therefore, let the parent handle them.
getWrapped().handle();
}
