It seems that I understand what is causing your problem. What application server are you using? Is it Glassfish 3.0.1? Because Glassfish 3.0.1 provides JSF 2.0 implementation but not JSF 1.2. So that you should probably read this article http://community.jboss.org/wiki/RichFaces333andJSF20.

I looked at these links:
http://www.coderanch.com/t/214435/JSF/java/JSF-as-RuntimeException-Cannot-find
http://www.coderanch.com/t/509611/JSF/java/jsf-java-lang-RuntimeException-Cannot
http://www.coderanch.com/t/522091/JSF/java/java-lang-RuntimeException-Cannot-find
And I think that you may have a conflict between JSF implementations. Look into links for details.
