Xerces calls SAXParserFactoryImpl but doesn't have it?

["Longstrom, Ed" <lo...@AtlasCommerce.com>]

Here is the error I am getting when attempting to invoke the newInstance
method from the SAXParserFactory class:

javax.xml.parsers.FactoryConfigurationError: Cannot load class
SAXParserFactory class "org.apache.xerces.jaxp.SAXParserFactoryImpl"

This file doesn't seem to be in the Xerces 1.1.1 or 1.1.2, but it is in one
of the Developer Releases http://xml.apache.org/from-cvs/xml-xerces/.  It
was just interesting since this is called by Xerces itself.

Any background on this?  And would it be wise to add this from the Dev
release to the current jar file?

Thanks.
