Access an external session in JSF

Question

Hi all,
I have an existing MVC application developed using JSP/Servlets. The session management is done using cookies.
I have writen a JSF application.
Now I have to integrate my JSF application to the existing JSP application and I want to access the same session that is initiated in my original JSP application at runtime.
Can somebody please give me some idea as to how to access this external session managed by cookies in my JSF application?
Any help is highly appreciated.
Thanks and regards,
Pram

Hi Pram,
I think the two "Map"s is deferent, first one for returning session data, the later one for returning cookie data.
As I known, session data is stored on the server. The session used a cookie named like "SessonId"(such as JSESSIONID) to link between client the server. The client known only the session id, not the data in the sesson.The cookie data is always store on the client side, which like a key-value pair.
The following is from JSF's javadoc:
>
abstract java.util.Map getRequestCookieMap()
Return an immutable Map whose keys are the set of cookie names included in the current request, and whose values (of type javax.servlet.http.Cookie) are the first (or only) cookie for each cookie name returned by the underlying request.
abstract java.util.Map getSessionMap()
Return a mutable Map representing the session scope attributes for the current application.
