you would probably need to pass it (the session object) or better still the
relevant object to the relevant class. If you think about it, the servlet is
responsible for monitoring and maintaining user level information so it
should be the servlets job to access the session information and pass it to
the relevant class in a form the class can understand. Making the class
dependant on the way session information is held on the server is a bad idea
as it doesnt allow you to change the way you store sessions or session
ifnormation easily.

I am finding the same problem with the smart servlet example. Did you find 
any other information or resources for this pattern?
