I receive a strange error relating to xerces on the app engine. My application runs fine in my local development environment.
I've tried everything: 1.) I have el-ri-1.0.jar in my WEB-INF/lib 2.) I have xerces.jar and xercesImpl.jar in my WEB-INF/lib 3.) I tried to use Saxon instead of xerces, and received a similar error.
