SAXParser for XSD Validation in JDK 1.7

This section describes a tutorial example on how to the Xerces2 SAXParser class included in JDK 1.7 to perform XSD validation on an XML document. The XSD document must be specified with SAXParser.setProperty() method.

To fix the XSD loading problem with SAXValidator.java, I revised the program using the SAXParser.setProperty() method to set the XSD document explicitly:

import org.xml.sax.Attributes;
import org.xml.sax.SAXException;
import org.xml.sax.SAXParseException;
import org.xml.sax.helpers.DefaultHandler;
class SAXValidatorJdk17 {
   public static void main(String[] args) {
      String schemaFeature 
         = "http://apache.org/xml/features/validation/schema";
      try {
         File x = new File(args[0]);
         String schemaLocation = args[1];
         SAXParserFactory f = SAXParserFactory.newInstance();

         SAXParser p = f.newSAXParser();

         DefaultHandler h = new MyErrorHandler();
      } catch (ParserConfigurationException e) {
      } catch (SAXException e) {
      } catch (IOException e) {
   private static class MyErrorHandler extends DefaultHandler {
      public void warning(SAXParseException e) throws SAXException {
         System.out.println("Warning: "); 
      public void error(SAXParseException e) throws SAXException {
         System.out.println("Error: "); 
      public void fatalError(SAXParseException e) throws SAXException {
         System.out.println("Fattal error: "); 
      private void printInfo(SAXParseException e) {
         System.out.println("   Public ID: "+e.getPublicId());
         System.out.println("   System ID: "+e.getSystemId());
         System.out.println("   Line number: "+e.getLineNumber());
         System.out.println("   Column number: "+e.getColumnNumber());
         System.out.println("   Message: "+e.getMessage());

Run it on JDK 1.7:

c:\Progra~1\Java\jdk1.7.0_07\bin\javac SAXValidatorJdk17.java

c:\Progra~1\Java\jdk1.7.0_07\bin\java SAXValidatorJdk17 
   dictionary_invalid_xsd.xml dictionary.xsd


   Public ID: null
   System ID: file:/C:/herong/dictionary_invalid_xsd.xml
   Line number: 3
   Column number: 49
   Message: cvc-complex-type.3.2.2: Attribute 
   'xsi:noNamespaceSchemaLocation' is not allowed to appear in element

   System ID: file:/C:/herong/dictionary_invalid_xsd.xml
   Line number: 7
   Column number: 22
   Message: cvc-datatype-valid.1.2.1: 'yes' is not a valid value for 


Interestingly, the "xerces" implementation included in JDK 1.7 does not like the attribute xsi:noNamespaceSchemaLocation="..." used in the XML document to specify the XSD document.
