Problem in xpath reading

Question

hi to all,
Iam using javax.xml.xpath.XPath to parse and read the xml file. It is working fine in java 1.5 version. but i want the same requirement in java 1.4. When iam using same code in java 1.4 it is throwing exceptions. Iam giving the code....
First of all iam creating XPathReader class for xpath parsing and reading.
import java.io.IOException;
import javax.xml.XMLConstants;
import javax.xml.namespace.QName;
import javax.xml.parsers.*;
import javax.xml.xpath.*;
import org.w3c.dom.Document;
import org.xml.sax.SAXException;
public class XPathReader {
private DocumentBuilder documentBuilder=null;
private Document xmlDocument;
private XPath xPath;
public XPathReader() {
initObjects();
private void initObjects(){
try {
documentBuilder= DocumentBuilderFactory.
newInstance().newDocumentBuilder();
xPath = XPathFactory.newInstance().
newXPath();
}catch (Exception ex) {
ex.printStackTrace();
public void parse(String filename){
try {
xmlDocument=documentBuilder.parse(filename);
} catch (Exception e) {
e.printStackTrace();
public Object read(String expression,
QName returnType){
try {
XPathExpression xPathExpression =
xPath.compile(expression);
return xPathExpression.evaluate
(xmlDocument, returnType);
} catch (XPathExpressionException ex) {
ex.printStackTrace();
return null;
In another class iam just creating object of XPathReader
XPathReader reader= new XPathReader();
reader.parse(....xml file path that which u want to parse......);
String expression = ....
NodeList rootNode = (NodeList)reader.read(expression,XPathConstants.NODESET);
here generally i will get NodeList object...
this code works fine in java 1.5
but it is showing exceptions in 1.4 as...
java.lang.RuntimeException: XPathFactory#newInstance() failed to create an XPathFactory for the default object model: http://java.sun.com/jaxp/xpath/dom with the XPathFactoryConfigurationException: javax.xml.xpath.XPathFactoryConfigurationException: No XPathFctory implementation found for the object model: http://java.sun.com/jaxp/xpath/dom
at javax.xml.xpath.XPathFactory.newInstance(Unknown Source)
I think XPathFactory is not in the 1.4. So, is there any alternative to overcome the above problem?
if any buddy knows please help me...
thanks to one and all...
