I tried to deploy the richfaces 4.1.M2 showcase to my local jboss server 7.0.1Final.

I packaged the the example using

mvn clean package -Pjbas7

and copy the war package to <JBOSS>/standalone/deployments

When jboss was started, I got the following exception.

6:58:37,207 ERROR [org.apache.catalina.core.StandardContext] (MSC service thread 1-2) Error listenerStart
