This is a sign of classpath pollution. JBoss already ships with JSF bundled. This exception can occur if you bundle JSF in your WAR as well. It'll only collide.

There are 2 solutions:

1. Get rid of jsf-api and jsf-impl JARs in your WAR (i.e. they should not end up in /WEB-INF/lib after build/deploy.

2. Tell JBoss that your WAR ships with its own version of JSF so that JBoss won't use its own.
