           <soapenv:Header>

              <urn:PackageVersionHeader>

                 <!--Zero or more repetitions:-->

                 <urn:packageVersions>

                    <urn:majorNumber>?</urn:majorNumber>

                    <urn:minorNumber>?</urn:minorNumber>

                    <urn:namespace>?</urn:namespace>

                 </urn:packageVersions>

              </urn:PackageVersionHeader>

              <urn:MruHeader>

                 <urn:updateMru>?</urn:updateMru>

              </urn:MruHeader>

              <urn:QueryOptions>

                 <!--Optional:-->

                 <urn:batchSize>?</urn:batchSize>

              </urn:QueryOptions>

              <urn:SessionHeader>

                 <urn:sessionId>?</urn:sessionId>

              </urn:SessionHeader>

           </soapenv:Header>

           <soapenv:Body>

              <urn:query>

                 <urn:queryString>?</urn:queryString>

              </urn:query>

Hi Vijay

Did you try using the createElementNS() method of the Document class instead of createElement()?

Document (Java Platform SE 6)

You might want to share your code if you require further help.

Hi Yeoh,

Yes, i have tried it actually the problem is i want to declare the namespace and refer it with the prefix.

code what i have tried

import java.io.*;

import java.net.MalformedURLException;

import java.net.URL;

import java.util.ArrayList;

import java.util.List;

public class SFDC_SoapHeaders {

  public static void main(String args[]) throws ParserConfigurationException, TransformerException, MalformedURLException

  {

// URL namespaceUrl = new URL("urn:enterprise.soap.sforce.com");

// String namespaceact = "xmlns:urn="+namespaceUrl.toString();

  DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();

  dbf.setNamespaceAware(true);

  dbf.setIgnoringElementContentWhitespace(true);

  dbf.setValidating(false);

  DocumentBuilder db = dbf.newDocumentBuilder();

  Document doc = db.newDocument();

  //Element Envelope = doc.createElement("Envelope");

  //.appendChild(Header);

  Element PackageVersionHeader = doc.createElement("PackageVersionHeader");

  Header.appendChild(PackageVersionHeader);

  Element packageVersions = doc.createElement( "packageVersions");

  PackageVersionHeader.appendChild(packageVersions);

  Element majorNumber = doc.createElement( "majorNumber");

  PackageVersionHeader.appendChild(majorNumber);

  majorNumber.setTextContent("0");

  //majorNumber.setPrefix("urn");

  majorNumber.setAttribute("urn", "urn=urn:enterprise.soap.sforce.com");

  Element minorNumber = doc.createElement("minorNumber");

  Element MruHeader = doc.createElement("MruHeader");

  Header.appendChild(MruHeader);

  Header.setPrefix("urn");

  Header.setAttribute("urn", "urn=urn:enterprise.soap.sforce.com");

  Element updateMru = doc.createElementNS("urn=urn:enterprise.soap.sforce.com","updateMru");

  MruHeader.appendChild(updateMru);

  updateMru.setPrefix("urn");

  updateMru.setAttribute("urn", "urn=urn:enterprise.soap.sforce.com");

  updateMru.setTextContent("1");

  Element QueryOptions = doc.createElement("QueryOptions");

  Header.appendChild(QueryOptions);

  Header.setPrefix("urn");

  Header.setAttribute("urn", "urn=urn:enterprise.soap.sforce.com");

  Element batchSize = doc.createElement("batchSize");

  QueryOptions.appendChild(batchSize);

  batchSize.setTextContent("1");

  Element SessionHeader = doc.createElement("SessionHeader");

  Header.appendChild(SessionHeader);

  Element sessionId = doc.createElementNS("urn=urn:enterprise.soap.sforce.com", "sessionId");

  SessionHeader.appendChild(sessionId);

  sessionId.setTextContent("Vijay");

  //SoapHeader soapheader = new SoapHeader(new QName(Header.getNamespaceURI(),

  // Header.getLocalName()), Header);

  //soapheader.setActor("actor_test");

  //soapheader.setMustUnderstand(true);

  StringWriter sw = new StringWriter();

  StreamResult result = new StreamResult(sw);

  DOMSource source = new DOMSource(Header);

  TransformerFactory tf =  TransformerFactory.newInstance();

  Transformer transformer = tf.newTransformer();

  transformer.transform(source, result);

  String xmlString = sw.toString();

  System.out.println(xmlString);

  }

}

Output it

<?xml version="1.0" encoding="UTF-8"?>

<urn:soapenv xmlns:urn="urn:enterprise.soap.sforce.com" urn="urn=urn:enterprise.soap.sforce.com">

  <PackageVersionHeader>

  <packageVersions/>

  <majorNumber urn="urn=urn:enterprise.soap.sforce.com">0</majorNumber>

  <minorNumber>2</minorNumber>

  <namespace>Vijay2</namespace>

  </PackageVersionHeader>

  <MruHeader>

  <urn:updateMru xmlns:urn="urn=urn:enterprise.soap.sforce.com" urn="urn=urn:enterprise.soap.sforce.com">1</urn:updateMru>

  </MruHeader>

  <QueryOptions>

  <batchSize>1</batchSize>

  </QueryOptions>

  <SessionHeader>

  <sessionId xmlns="urn=urn:enterprise.soap.sforce.com">Vijay</sessionId>

  </SessionHeader>

</urn:soapenv>

Kindly help me in solving the issue.

I think the usage of the method is incorrect.

It should be like that

Element updateMru = doc.createElementNS("urn:enterprise.soap.sforce.com","urn:updateMru");

The first argument is the namespace, the second is the name of the element with a prefix.

Also try to comment out the setAttribute() calls.

Try this out and see how your output looks like.
