Today I found the reason why my ear/web application did not work in Glassfish V 2.1.1. (it works in V 2.1.0) The app deploys but when I try to open the Web context URL I see the following exception in glassfish server.log:
sending context initialized event to listener instance of class
com.sun.faces.config.ConfigurationException: CONFIGURATION FAILED! This
parser does not support specification "null" version "null" at
After some searching I think that the problem was forced by some additional libraries which I provided in my web module.
So after I removed my axiom-api dependency (maven 1.2.7) and I removed xercesImpl-2.6.2 the app works fine again.
