Hi all.

I'm attempting to configure JSF 2.0 to run on Google App Engine using the following setup:

Apache Xalan-J 2.9.0
Google AppEngine for Java SDK v1.2.5
Sun Java ServerFaces 2.0 FCS
Unified Expression Language 1.1 API (el-api-1.1.jar) and Implementation (el-impl-1.1jar)

I followed the procedure indicated in http://java.wildstartech.com/Java-Platform-Enterprise-Edition/JavaServer-Faces/sun-javaserver-faces-reference-implementation/configuring-jsf-20-to-run-on-the-google-appengine

However, I am getting the following errors on startup. I was wondering if anyone has experienced this problem.
