Ivan- It looks like you're right that the schema isn't being read. The way I made sure my schemaLocation attribute was set correctly in my XML file was by printing out the contents of the "user.dir" system property and setting the schemaLocation relative to that.
Hope that helps.

I'm having a problem with XML Schema validation - it's as if the schema isn't being read. I'm parsing personal-schema.xml from the Xerces-J 1.3.0 distribution, and I've put together a simple program to parse the document: import java.io.IOException; import org.xml.sax.Attributes; import org.xml.sax.ErrorHandler; import org.xml.sax.Locator; import org.xml.sax.SAXException; import org.xml.sax.SAXParseException; import org.xml.sax.XMLReader; import org.xml.sax.helpers.DefaultHandler; import org.xml.sax.helpers.XMLReaderFactory; public class Parser extends DefaultHandler { private XMLReader m_reader; public Parser() throws SAXException { // create the parser (controlled by the org.xml.sax.driver property) // pick up the Apache Xerces parser by default if (System.getProperty("org.xml.sax.driver") == null) { System.setProperty("org.xml.sax.driver", "org.apache.xerces.parsers.SAXParser"); } m_reader = XMLReaderFactory.createXMLReader(); // register XMLParser as the handler with the SAX parser m_reader.setErrorHandler(this); // switch on namespaces... m_reader.setFeature("http://xml.org/sax/features/namespaces";, true); // and validation m_reader.setFeature("http://xml.org/sax/features/validation";, true); } public void parse(String fileName) throws SAXException, IOException { // parse the document m_reader.parse(fileName); } // ErrorHandler interface public void warning(SAXParseException ex) { System.out.println("Warning: " + ex); } public void error(SAXParseException ex) { System.out.println("Error: " + ex); } public void fatalError(SAXParseException ex) { System.out.println("Fatal error: " + ex); } // Test code public static class Test { public static void main(String[] args) { if (args.length < 1) { System.err.println ("Usage: Parser$Test <xmlFile>"); System.exit(1); } else { try { Parser parser = new Parser(); parser.parse(args[0]); System.out.println("Finished parsing"); } catch (SAXException ex) { ex.printStackTrace(System.err); } catch(IOException io) { io.printStackTrace(System.err); } System.exit(0); } } } } When I run this code, passing personal-schema.xml as the file to parse, I get the following output: Error: org.xml.sax.SAXParseException: Element type "personnel" must be declared.

Finished parsing Does anyone have any suggestions how I can fix this to get the parser to recognise the schema? By the way, the schema, xml instance and class are all living in the same directory.
