XML parsing inside some webservices

Question

Hi,
I made some webservice where I tryed to use some XML parser made myself. The XML parser works fine in other implementation, but doesn't in this particular case.
It looks like the Oracle OC4J handles some XML and parses itself with worng result. After parsing procedure I obtian final result by calling:
document.getDocumentElement().toString();
In other situation I get there XML String after parsing routine, but the same inside webservice on OC4J gives result as below:
oracle.xml.parser.v2.XMLElement@93
What's a reason of two different results?
Thanks for some help

Hi Krzysztof,
If you are looking to convert a DOM to a String I would recommend using one of the following approaches instead of using the "toString()" method.
XDK
import java.io.FileReader;
import java.io.StringWriter;
import oracle.xml.parser.v2.DOMParser;
import oracle.xml.parser.v2.XMLDocument;
import oracle.xml.parser.v2.XMLElement;
import org.w3c.dom.Node;
public class Test {
    public static void main(String[] args) throws Exception {
        FileReader reader = new FileReader("xpath.xml");
        DOMParser parser = new DOMParser();
        parser.parse(reader);
        XMLDocument xmlDocument = parser.getDocument();
        XMLElement xmlElement = (XMLElement)xmlDocument.getDocumentElement();
        StringWriter stringWriter = new StringWriter();
        xmlElement.print(stringWriter);
        String string = stringWriter.toString();
        System.out.println(string);
JAXP
import java.io.File;
import java.io.StringWriter;
import javax.xml.transform.Transformer;
import javax.xml.transform.TransformerException;
import javax.xml.transform.TransformerFactory;
import javax.xml.transform.stream.StreamSource;
import javax.xml.transform.stream.StreamResult;
public class Test {
    public static void main(String[] args) {
        try {
            File file = new File("sample.xml");
            StreamSource source = new StreamSource(file);
            StringWriter stringWriter = new StringWriter();
            StreamResult result = new StreamResult(stringWriter);
            TransformerFactory transformerFactory = TransformerFactory.newInstance();
            Transformer transformer = transformerFactory.newTransformer();
            transformer.transform(source, result);
            String string = stringWriter.toString();
            System.out.println(string);
        } catch (TransformerException e) {
            // Handle the exception
            e.printStackTrace();
