It's more than likely geronimo-jcdi jar that's causing the problem. Weld looks to see if Extension class equals Extension class and since there are two independent instances on the classpath, it breaks the comparison. 9/10 this is the source of a class not found problem.

Java EE APIs should never be provided by an archive when deploying to a compliant app server. If you were moving from Tomcat to JBoss AS it's important to keep that in mind.

I doubt the apache-commons libraries would present a problem, so you can likely leave those.

Aha, as I thought you are bundling in the war all sorts of stuff which AS6 provides (and doesn't support overriding simply by placing in the war).

Try removing at least:

* geronimo*
* javassist
* jsr250-api
* myfaces-api
* myfaces-impl
* openwebbeans*
* scannotation

you may also need to remove commons-XXX which duplicate that in the AS
