One way to do it is to use two beans, first for the login and scond for your
info page.
your login page is the start page where you would create the bean instance
and make it a session scoped.
Import this bean instance in your second page, if it is not in session then
send it to the login jsp page.
while sending him to the login page attach the url of the current page as a
part of query string so that when he successfully logs in, he can come back
to the same page where he was. This is all done when the session expires
before the user can see the second page
If the login session expires while he is entering values in the current
page, then you can save all these values in the second page's bean before
forwarding him to the login page, when the user comes back to the same page
after logging in, then get the bean's properties and populate the form
fields. ( You can add stuff to query string to check your state, whether you
are coming back to the same page after typing some stuff or it is a fresh
start.
Hope this helps.
