Hi, we've had the same problem! it seems that Web sphere 6.0 ships with
IBM's JSF distribution and probably it's in the server's boot classpath
as well. We didn't manage to sort out the problem in a decent way. If
you just want your web app to work you have to swap the jars in the
server's lib (hope you can do that). Substitute myfaces.jar to
ibm-jsf-impl.jar (check the name of this jar. I'm not sure about that)
and start the server again. Obviously it's not a viable solution in a
production environment but at least you can work around the problem in
your test environment.
Hope this helps
cheers
