Why do you report this error? I'm using a xom-1.2.10.jar.

 PackageXML2;ImportJavax.xml.parsers.SAXParser;Importjavax.xml.parsers.SAXParserFactory;ImportNu.xom.Builder;ImportOrg.xml.sax.XMLReader; Public classXOM { Public Static voidMain (string[] args)throwsException {saxparserfactory Factory=saxparserfactory.newinstance (); Factory.setvalidating (false); Factory.setnamespaceaware (true); SAXParser Parser=Factory.newsaxparser (); XMLReader Reader=Parser.getxmlreader (); Reader.seterrorhandler (NewSimpleerrorhandler ()); Builder Builder=NewBuilder (reader); Builder.build ("File:\\h:\\mycodes\\java\\jbpm\\xml2\\contacts.xml"); }}

It's inconvenient to start using the file protocol from Xom-1.2.10.jar.
