I'm using SEAM 2.2 for a web application. I wanted an auditing tool and found picketbox does it. So I decided to use it with seam. Also picketbox has authentication and role mapping support. Is it a wise idea to use picketbox authentication, authorisation and rolemapping and auditing with seam? Also its bit difficult to deal with the current documentation of the picketbox for a newbie as me to use it, is there a step by step guide or such for using picketbox?
