Well, the myfaces-extensions are designed to be independent of JSF implementation, so it should work with JSF RI. I've taken a glance to the source of this custom component and I see there is a dependency on Apache commons validator (commons-validator.jar). Do you have this jar in the classpath? If yes could you post your stacktrace?
