Hi
In any project we can set values to the session.and get value from the session. which place or path the session information to be stored.

Thanks in advance

(assuming you're talking abt HTTP Sessions) AFAIK they are stored in memory and not serialized to any normal flat file. (although you might wanna check if HttpSession class implements serialize or not)

The server can serialise sessions as needed, but you don't need to worry about that and shouldn't care.
