title: web.xml required in Spring applications
body: <p>A Spring web application is just a normal web application using servlet API 3.0.<br>
  In servlet API 3.0 web.xml file is optional (most of the time).
  I' ve tried not to include web.xml inside my Spring aplication,but somehow it seems to be required even using Servlet 3.0</p>
  
  <p>The only difference between a Spring applications and web apps I've run successfully without writing a web.xml file, is that in Spring filters and servlets are defined inside jars in the lib folder.</p>
  
  <p>Any clues why this happens ?</p>
