If you just need access to the Request Attributes, try implementing
RequestAware in your action. If you need access to other, more
Servlet specific, parts of the Request, you'll have tto implement
ServletRequestAware. Similarly for Sessions, if you just need the
attributes, implement SessionAware, if you need full access implement
ServletRequestAware and call request.getSession().
