Hi,
When you add <jsp:useBean id = "something" scope = "session" class="someclass"
/> in your first page, this will do :
- crearte an instance of type someclass named something and put that instance in
the session object using session.putValue(..) or session.setAttribute(..)
Then in other pages of the same application, if you want to use an instance, it
is the same as in a class, you have to specifiy how to get that instance . In jsp
ypou have to include <jsp:useBean id = "something" scope = "session"
class="someclass" /> the engine will fist look for a someclass object named
something in the session object and use it if found else create it. If you want you
could also get the object directly using session;getValue(something) ot
getAttribute(something)
Hope this answer your question
Regards
Veronique
