Hi chris,

<init-params> specified in a <servlet> tag in the web.xml-<web-app>
context can be made available via the
ServletConfig.getInitParameter("name").

If you put them in <context-param> in the <web-app> they can be made
available
via the ServletContext object (instead of the ServletConfig as above)
--> ServletContext sc =3D ServletConfig.getServletContext()
    sc.getInitParameter("name")
