This is because when you run code inside an application server you typically don't have much control over the current working directory. So when you parse some XML using request.getInputStream() the parser has no idea where to look for the DTD / XSD file other than the current directory and hence it can't find it.
The typical way to solve this problem is to attacha SAX EntityResolver to the SAXReader so that you can read the DTD or schema file from whereever you wish, the classpath, ServletContext, a website near you or whatever. There's details here... http://www.mail-archive.com/dom4j-user@lists.sourceforge.net/msg00829.html James ------- http://radio.weblogs.com/0112098/ ----- Original Message ----- From: "Sahu, Santosh Kumar" <[EMAIL PROTECTED]> To: "James Strachan" <[EMAIL PROTECTED]> Sent: Wednesday, August 21, 2002 2:07 PM Subject: RE: SchemaValidation problem:please looking for quick reply HI , Thant progme is working fine as a standlalone programe. but when i run it in OC4j: i am getting the below:error: <errors> <error column="7" line="1">Document root element "Sale", must match DOCTYPE root "null".</error> <error column="7" line="1">Document is invalid: no grammar found.</error> </errors> this is expecting a DTD all the time when i am running in OC4j.

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.
