Im working with a JNDI realm to control access to a site. I need to be
able to 'trap' a successful login to any one of the pages in the site so
that I can create a session bean with login information. Is it possible
to tie a filter or valve to the login process and get the information
*before*
Put a filter on your application, in this filter, check if there is
currently a principal, if yes, check if there is already your bean in
the session. If not, create it. Then forward to the next of filter chain.
As you are in a filter, you will be notified before the servelt / JSP
