title: Manual for updating JSF 2.0 Project to 2.2
body: <p>unfortunately there are no working tutorials to update a Eclipse (KEPLER) JSF 2.0 Project to JSF 2.2.
  Should this update be done or should a new project be created (and import all files)?</p>
  
  <p>What are the Steps to update the used JSF version properly and clean?</p>
  
  <p>I'm just getting errors (from FactoryNotFound to StartupServletContextListener problems), when I change the faces.xml header to: </p>
  
  <pre><code>&lt;faces-config
  xmlns="http://java.sun.com/xml/ns/javaee"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-facesconfig_2_0.xsd"
  version="2.0"&gt;
  </code></pre>
  
  <p>I additionally updated the library to Majorra 2.2.0 (JSF 2.2) and dynamic web project to 3.0 and java to 1.7 (in the preferences), but the server just prints errors and does not work...</p>
