I usually download the latest Mojarra jar from https://maven.java.net/content/repositories/releases/org/glassfish/javax.faces/ or http://repo1.maven.org/maven2/org/glassfish/javax.faces/ and replace the old 'javax.faces.jar' file in C:\glassfish-4.1\glassfish\modules\
With Mojarra 2.2.10, they did not upload the new jar file to either of the above sites, I can only get the following 2 jar files:
These two files do not work in Glassfish.
Should I combine them manually and how? Or am I doing it the wrong way to begin with?
Have a look again. The file you are looking for IS available for download!
