Re: [jetty-user] JSF 2.2 helloWorld + mvn jetty:run = CONFIGURATION FAILED! com.sun.faces.vendor.WebContainerInjectionProvider cannot be cast to com.sun.faces.spi.InjectionProvider

Stephen,

Your configuration includes the jsf jars twice - once as dependencies
of the webapp and then again as dependencies of the jetty maven
plugin. This means the classes are loaded by both the webapp
classloader and the container classloader, leading to conflicts.

Remove the api and impl jars from the webapp dependecies as they
should only be container dependencies.

Also see the section on using JSF with jetty here:
http://www.eclipse.org/jetty/documentation/current/configuring-jsp.html#jsp-support
