You'll be able to get access to all those context-param elements if you have access to the ServletContext. You have access to the ServletConfig in a number of places, namely, Servlet#init(..), Filter#init(..), and most of the listener types.

The method you are looking for is ServletContext#getInitParameterNames().

Otherwise, you will have to parse the web.xml yourself.
