How to check if the user is logged in in JSF

[Ahmad Qatramiz]

I need to know if the user is logged in, if not will be redirected to login page.

How can i do this?

Hi,

Store some token in the session object.

If that token (let's say isLoggedIn) is avaliable (which will be stored upon successful login), then the user is in.

Otherwise, do your normal redirection.

Actually, in most cases the mere existence of a session means you're logged in - depending on what you define as "logged in". However, to accurately test for a session, you should make sure that you call the get session method with the right option. Otherwise get session will create a session if one didn't already exist, so it would always say you were logged in, even if you hadn't authenticated or set up whatever session parameters your login process might initialize.
