Java EE (Java Enterprise Edition) General Discussion

I am trying to get DOM and perform some XPATH operations on them.
I am stuck at getting the DOM in the first place.

I have following jars in the classpath.

C:/weblogic/lib/xml/jaxp.jar;\
C:/weblogic/lib/xml/parser.jar;\
C:/weblogic/lib/xml/xalan.jar;\
C:/weblogic/lib/xml/xml-apis.jar;\
C:/weblogic/lib/xml/xercesImpl.jar

I have set the System properties properly
javax.xml.transform.TransformerFactory=org.apache.xalan.processor.TransformerFactoryImpl
javax.xml.parsers.DocumentBuilderFactory=org.apache.xerces.jaxp.DocumentBuilderFactoryImpl
javax.xml.parsers.SaxParserFactory=xorg.apache.xerces.jaxp.SaxParserFactoryImpl

This the segment of the code that is throwing error.

DocumentBuilder builder;
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
factory.setNamespaceAware(true);
factory.setValidating(true);
StringReader str = new StringReader(XMLField);
InputSource input = new InputSource(str);
String location = "/Company.xml";
try {
builder = factory.newDocumentBuilder();
Document document = builder.parse(location);
} catch (SAXException se) {
// handle error
} catch (IOException ioe) {
// handle error
}
catch (ParserConfigurationException pce) {
// handle error
}


Would somebody please help. I have spent 3 days on this, with not much success.
