I've just been dealing with this sort of issue myself, running MyFaces on Glassfish. It turns out to be a classloading issue that in this case could only be solved by specifying
<class-loader delegate="true"/> in sun-web.xml. This is in fact the default setting but was set to false because I had been following http://weblogs.java.net/blog/2008/12/11/totd-59-alternative-jsf-implementations-glassfish-myfaces-and-tomahawk these instructions in this post by a Sun developer on how to use MyFaces on Glassfish.
