Note this blog is obsolete, see for the current blog Since Mojarra is available as a standalone JAR you can opt to update your Glassfish installation with a newer version. How would you do that? Well it is simple. 
  1. Make sure your Glassfish container is not running
  2. Grab the latest JAR from
  3. Replace the javax.faces.jar in the modules directory of your Glassfish directory with the downloaded JAR file
  4. Start your Glassfish container
And that is it. Enjoy!
