DTD validation

Question

Hi All,
I am using Sax parser (jaxp1.1), I have directed to validate the xml using setValidating(true), even then it is not validating the data against DTD spec.
PLease let me know the possible things to be checked.
Thanks

Hi , I am passing the handler of present class to the parser.
My Code looks like
import javax.xml.parsers.*;
import org.xml.sax.*;
import org.xml.sax.helpers.*;
import java.util.*;
import java.io.*;
public class Stores extends DefaultHandler {
// Instance variables
Hashtable stores;
Hashtable storeInfo;
public Hashtable returnStores() {   
return stores;
public Hashtable getStoreInfo() {
String xmlFile = "Print.xml";
Stores wpInstance = new Stores();
DefaultHandler wpHandler = wpInstance;
SAXParserFactory factory = SAXParserFactory.newInstance();
factory.setValidating(true);
try {
SAXParser saxParser = factory.newSAXParser();
saxParser.parse(new File(xmlFile), wpHandler);
} catch (SAXParseException spe) {
System.err.println("\n ** Parsing error " + ", line " + spe.getLineNumber() +
", uri " + spe.getSystemId());
System.err.println(" " + spe.getMessage());
// Catch the contained Exception, if exist
Exception ex = spe;
if( spe.getException() != null) ex = spe.getException();
ex.printStackTrace();
} catch (SAXException sxe) {
Exception ex = sxe;
if (sxe.getException() != null) ex = sxe.getException();
ex.printStackTrace();
} catch (ParserConfigurationException pce) {
pce.printStackTrace();
} catch (IOException ioe) {
ioe.printStackTrace();
return wpInstance.returnStores();
// Buffer for collecting data from
// the "characters" SAX event.
private CharArrayWriter contents = new CharArrayWriter();
public void startDocument() throws SAXException {
stores = new Hashtable();
}
