Valider Document op imod et xsd

Jeg lavede engang dette eksempel på validering af XML dokument mod skema:

import java.io.File;
import java.io.IOException;

import javax.xml.parsers.FactoryConfigurationError;
import javax.xml.parsers.ParserConfigurationException;
import javax.xml.parsers.SAXParser;
import javax.xml.parsers.SAXParserFactory;

import org.xml.sax.SAXException;
import org.xml.sax.SAXNotRecognizedException;
import org.xml.sax.SAXNotSupportedException;
import org.xml.sax.SAXParseException;
import org.xml.sax.helpers.DefaultHandler;

public class ValWithSaxAndSchema {
  static final String JAXP_SCHEMA_LANGUAGE =
      "http://java.sun.com/xml/jaxp/properties/schemaLanguage";
  static final String W3C_XML_SCHEMA =
        "http://www.w3.org/2001/XMLSchema";
  static final String JAXP_SCHEMA_SOURCE =
      "http://java.sun.com/xml/jaxp/properties/schemaSource";
  public static void main(String[] args) {
      try {
        SAXParserFactory factory = SAXParserFactory.newInstance();
        factory.setNamespaceAware(true);
        factory.setValidating(true);
        SAXParser saxParser = factory.newSAXParser();
        saxParser.setProperty(JAXP_SCHEMA_LANGUAGE, W3C_XML_SCHEMA);
        saxParser.setProperty(JAXP_SCHEMA_SOURCE, new File(args[1]));
        saxParser.parse(new File(args[0]), new ValHandler());
      } catch (SAXNotRecognizedException e) {
        e.printStackTrace();
      } catch (SAXNotSupportedException e) {
        e.printStackTrace();
      } catch (FactoryConfigurationError e) {
        e.printStackTrace();
      } catch (ParserConfigurationException e) {
        e.printStackTrace();
      } catch (SAXException e) {
        e.printStackTrace();
      } catch (IOException e) {
        e.printStackTrace();
      }
  }
}

class ValHandler extends DefaultHandler {
    public void error(SAXParseException e) {
        e.printStackTrace();
    }
    public void warning(SAXParseException e) {
        e.printStackTrace();
    }
}

args[0] = XML dokument
args[1] = skema

OK ?
