If you have xerces.jar on your classpath and want to ensure that you use the Xerces parser with dom4j, irrespective of the presense or configuration of JAXP or the SAX system property you can do the following...
SAXReader reader = new SAXReader( new org.apache.xerces.parsers.SAXParser() ); ... That will hardwire xerces in and can save you trouble if your app server, such as OC4j, tries to force its own parser on you.

The bundled aelfred parser doesn't do validation very well, so I'd suggest using xerces or crimson. I would have though that one of those comes with Oracle. In which case either add the JAXP jars (these days its called xml-apis.jar and comes with xerces) to your classpath or explicitly create the XMLReader / SAXDriver / SAXParser implementation that comes with the parser you're using, like Xerces. this line... org.dom4j.io.aelfred.SAXDriver saxdriver=new org.dom4j.io.aelfred.SAXDriver(); will ensure that the Aelfred parser will always be used, irrespectively of whether Xerces is on the classpath or not.

The stack trace demonstrates the problem - crimson is on your classpath first, so its not actually using Xerces. You'll need to mess around with your classpath to put xerces in front of crimson.
