JSF Storing data into a cookie

Question

I want to store some user data into a cookie so it's always there when they load the web app, even if the session has expired.

What's the best way of doing this with JSF?

Cookies may be the wrong approach here. Cookies are for communication from the client to the server. If you want client-side storage, you should maybe look at DOM Storage. — Kerrek SB, Jul 20 '11 at 14:15

Writing to a cookie:

FacesContext.getCurrentInstance()
 .getExternalContext()
 .addResponseCookie("CookieName", "value", null);

Reading the cookie

Map<String, Object> requestCookieMap = FacesContext.getCurrentInstance()
   .getExternalContext()
   .getRequestCookieMap();

If you're planning on adding properties, you could also use "FacesContext.getCurrentInstance().getExternalContext().getResponse()", cast it to HttpServletResponse, and then use "resp.addCookie(Cookie c)". – Aug 01 '13 at 17:33

I'm using JSF2.2 and this answer didn't work. If you had the same issue try this answer: http://stackoverflow.com/questions/20934016/how-to-add-cookie-in-jsf – Yamada Aug 28 '14 at 17:05
