I have to pass object,so I think I should go for session?
Am I right?
Yes, you should use session, but ... i dissuade from save something to
session from JSP. Firstly, after a month you won't remember what you
have in session, and session will grown because you won't remember to
clean it probably. Besides, any logic you can do in view, you can and
should do in action.
If you want to remember something from one request to another and if you
use the same action as input action and action you submit to, you can
store action object (in s2 or ScopeInterceptor) or action form (in s1)
is session. If you want to remember something across different actions
save it as normal object in session.
The are 2 other things with session:
-- any object you put into session should be serializable (less troubles
when you cluster application for example)
-- session is like memory in C/C++, it can grows when is bad used; you
have to remember to clean it when you know you don't need some objects
anymore, and use session as small as possible. Remember that each user
has session.
