In case of ServletRequest, we provide the path relative to http request while in the case of ServletContext we provide path relative to root of context.

  If we use ServletRequest object then we have to give only the servlet name. For ServletContext object we have to give the relative path i.e, in a context we have more than servlet instances. so we have to give the path from context level.
