Dúvida com RichFaces no Tomcat

Programação Java
#1

Caros,
tenho uma aplicação JSF 1.2 que roda normalmente no Tomcat 6.No entanto,quando tento adicionar o RichFaces estou tendo o seguinte problema:

SEVERE: Exception sending context initialized event to listener instance of class com.sun.faces.config.ConfigureListener
com.sun.faces.config.ConfigurationException: CONFIGURATION FAILED! org.ajax4jsf.renderkit.ChameleonRenderKitFactory

Segue o web.xml

Achei o que era.
As libs do JSF também estavam no WEB-INF/lib do projeto.Tirei e funcionou.
Obrigado.
