Resolution:


Removing 2 jars: jsf-api.jar and jsf-impl.jar removed the exception for me. However, some other jars that may have to be removed: el-api.jar, el-ri.jar, jsf-tlds.jar

The exception is caused, apparently, due to a versioning issue between the jars in the lib of the Web Application and the jars in the JBoss Application Server.
