title: Which XML namespace to use with JSF 2.2 and up
body: <p>I have migrated my application from JSF 1.2 to 2.2. </p>
  
  <p>It used XML namespaces on <code>java.sun.com</code> domain like  <code>xmlns:f="http://java.sun.com/jsf/core"</code>. However, <a href="http://www.oracle.com/webfolder/technetwork/tutorials/obe/java/HTML5-JSF/html5jsf.html" rel="noreferrer">Oracle's Java EE 7 tutorial</a> is using XML namespaces on <code>xmlns.jcp.org</code> domain like 
  <code>xmlns:f="http://xmlns.jcp.org/jsf/core"</code>.</p>
  
  <p>Which one is recommended and why was this changed?</p>
