In a servlet J2EE application, there is an init style method that gets
called after that servlet is loaded. Is there something similar within
a rails controller context. I am looking for something where I can load
and setup a particular object.
Also, what about with sessions as well. I would like to call some
library when a user session begins and possibly kill that object when
the session ends.

Perhaps you want a before_filter?

Sessions are usually automatically created on Rails, by default, upon
first access. So it seems doubtful that there is a special callback,
since they are “nothing special”. However, you can easily setup a
global method (through ApplicationController) that would
setup/teardown session, something like start_session/end_session.
