Path Elements?

I am reading the Sybex study guide, and there's a section that covers Path Elements:
Request URI = contextPath + servletPath + pathInfo
and the following examples were given:
Request path: /games/tictactoe/welcome.html
-Context path = /games
-Servlet path: /tictactoe
-Path info: /welcome.html
Request path: /games/registration/StartServlet
-Context path: /games
-Servlet path: /registration/StartServlet
-Path info: null
Request path: /games/Search/1234?query=Yamaha+R6
-Context path: /games
-Servlet path: /Search
-Path info: /1234
I am wondering if there's an easy way of telling which path is which. For example, in the last example, can it also be Context path: /games/Search, Servlet path=/1234 and Path info=null? How can one tell the servlet path from the path info?
Thanks,
Adrian
