The most likely cause of this is that xerces.jar is not in the location
where you think it is or it is corrupted or you have an older version of
xerces or another parser earlier in your classpath.  Double check the
xerces.jar for its correct location and make sure you don't have any
other parsers in your classpath.

HTH,
