You are trying to run RF on Websphere, right?
Problem is that Websphere has a JSF 1.1 implementation that is not sufficient for RF 3.2 and leads to conflicts if you add a JSF 1.2 implementation into your application.
To resolve this issue, you must change class loader order for your app to "PARENT_LAST".
Of course you need to include jsf 1.2 implementation (e.g. the RI from Sun) in your app.
