The ServletContext returned from ServletConfig and from
HttpSession are the same instance, the one instance that
exists while the web application is running. You can confirm
it with a debugger.
The main differences though are that you get a reference to
ServletConfig when in a Servlet and you get a reference to
an HttpSession from an HttpServletRequest.
You can get a reference to a ServletContext from a
FilterConfig when in a Filter.
If you are not in a Servlet and don't want to create an
HttpSession through a call to
HttpServletRequest.getSession() to be able to get a
reference to a ServletContext then create a Filter which
puts a reference to the ServletContext in a request attribute.
