1) How to send the request to show the next page?
You can do paging by capturing the first and last record numbers as a
hidden variable.
2) Is it a performant solution to store all the data in a session variable
(vector)?
my suggestion would be make a java class with mutator methods and send only
the object of that clas sin the session and not hte whole vector.
3) When can I decide to remove all the data from the session?
as soon as the user logs out of the system and when you call
logoutservlet
hope this helps.

Ramesh Kesavanarayanan.
