Should I use a persistence layer?

["Chen, Dean (Zhun)" <De...@gs.com>]

Hi,

For an web application, is there a way for a user to paginate through
(similar to google) a lot of data across multiple browser windows.

The usual way of paginating with session scope works fine. However, if a
user has 2 windows open on the same application. When he/she queries on one,
then queries on another, and then comes back to the first window and click
"Next", he/she will get bad results.

Does this lead to EJB or any other persistence layers?

Thanks,


Dean Chen
