Not able to Pass header info to Microsoft MapPoint WebService using WLS10

Question

We are passing some Header info to the MapPoint Web Service from our client Web Service which is hosted in Weblogic 10, however we are not sure if the info is getting passed.
The actual soap header which we are trying to postis as below:
<env:Header xmlns:env="http://schemas.xmlsoap.org/soap/envelope/">
<m:CustomerInfoFindHeader xmlns:m="http://s.mappoint.net/mappoint-30/">
<m:CustomLogEntry>2</m:CustomLogEntry>
</m:CustomerInfoFindHeader>
</env:Header>
We are using the below code snippet for setting the header:
Document doc = null;
try
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
factory.setNamespaceAware(true);
doc = factory.newDocumentBuilder().newDocument();
catch(ParserConfigurationException pce)
System.out.println("ERROR -> " + pce.getMessage());
Element header = doc.createElementNS("http://schemas.xmlsoap.org/soap/envelope/", "SOAP-ENV:Header");
Element headerContent = doc.createElementNS("http://s.mappoint.net/mappoint-30/","m:CustomerInfoFindHeader");
Element headerChildContent = doc.createElementNS("http://s.mappoint.net/mappoint-30/", "m:CustomLogEntry");
headerChildContent.appendChild(doc.createTextNode("2"));
headerContent.appendChild(headerChildContent);
header.appendChild(headerContent);
Attr nsAttr = doc.createAttributeNS("http://www.w3.org/2000/xmlns/","xmlns:m");
nsAttr.setValue("http://s.mappoint.net/mappoint-30/");
headerContent.setAttributeNodeNS(nsAttr);
findServiceControl.setOutputHeaders(new Element[] {header});
Here findServiceControl is the Service Control object.
Even if the code is not throwing any error/exception I am not able to see the header portion which invoking the Mappoint Web Service (using the weblogic test client for testing the webservice).
Is there any other methodology for setting the header.

If you're not sure the header is being created properly, you should switch to using a javax.xml.transform.stream.StreamSource and javax.xml.transform.dom.DOMResult. For instance:
import java.io.ByteArrayInputStream;
import javax.xml.transform.TransformerFactory;
import javax.xml.transform.Transformer;
import javax.xml.transform.dom.DOMResult;
import javax.xml.transform.stream.StreamSource;
import org.w3c.dom.Document;
import org.w3c.dom.Element;
StringBuffer xml = new StringBuffer()
.append("<env:Header ")
.append("xmlns:env=\"http://schemas.xmlsoap.org/soap/envelope/\">")
.append("<m:CustomerInfoFindHeader xmlns:m=\"http://s.mappoint.net/mappoint-30/\">")
.append("<m:CustomLogEntry>2</m:CustomLogEntry>")
.append("</m:CustomerInfoFindHeader>")
.append("</env:Header>);
TransformerFactory xformFactory = TransformerFactory.newInstance();
Transformer transformer = xformFactory.newTransformer();
ByteArrayInputStream bais = new ByteArrayInputStream(xml.toString().getBytes());
DOMResult result = new DOMResult();
transformer.transform(new StreamSource(bais), result);
Document document = (Document)result.getNode();
findServiceControl.setOutputHeaders(new Element[] {document.getDocumentElement()});
If you want to see the SOAP request being sent to the Mappoint Web Service, add the following to the JAVA_OPTIONS environment variable (in the startWebLogic.cmd file), and bounce it:
-Dweblogic.wsee.verbose=*
-Dweblogic.log.RedirectStdoutToServerLogEnabled=true
This will write the SOAP request (and SOAP response) to the server log of the WebLogic Server instance, which the service control is running in.
