Soap envelope header and WebServiceMessageCallback

[MrKimi]

I am trying to add a customised header to my soap message and I use a WebServiceMessageCallback.soWithMessage to add it.

I've tried several things, influenced by examples on this forum but no luck yet. They do something to the message but not actually what I was hoping to see.

...
    SoapMessage soapMessage = (SoapMessage) message;
    SoapHeader header = soapMessage.getSoapHeader();
    
    StringBuffer sbHeader = new StringBuffer();
    sbHeader.append("<hdrns:MyHeader xmlns:hdrns=\"http://www.company.com/foo/bar/MyHeader.xsd\" ID=\"myHdr\">")
        .append("<hdrns:MessageID>")
        .append("1234")
        .append("</hdrns:MessageID>")
        .append("</hdrns:MyHeader>");
    
    StringSource mefHeaderSource = new StringSource(sbHeader.toString());
    SoapHeader soapHeader = ((SoapMessage) message).getSoapHeader();
    Transformer transformer = TransformerFactory.newInstance().newTransformer();
    transformer.transform(mefHeaderSource, soapHeader.getResult());
...

The above is one of the example I found here and the result I got was:

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
   <soapenv:Header>
      <hdrns:MyHeader soapenv:mustUnderstand="0" xmlns:hdrns="http://www.company.com/foo/bar/MyHeader.xsd"/>
   </soapenv:Header>
   <soapenv:Body>

Huh? It obviously added something to the header because the top element is there but not the child element. I must have missed a step.

I haven't specified the message handler and it defaulted to Saaj.

Spring-ws 1.0.2
saaj-1.4

Thanks

I can't find any error in the code, it looks good.

As an alternative, you could try:

SoapHeaderElement headerElement = soapHeader.addHeaderElement(new QName("http://www.company.com/foo/bar/MyHeader.xsd", "MyHeader");
headerElement.addAttribute(new QName("ID"), "myHdr");
StringBuffer sbHeader = new StringBuffer();
sbHeader.append("<hdrns:MessageID xmlns:hdrns=\"http://www.company.com/foo/bar/MyHeader.xsd\")
        .append("1234")
        .append("</hdrns:MessageID>");
    
    StringSource mefHeaderSource = new StringSource(sbHeader.toString());
    Transformer transformer = TransformerFactory.newInstance().newTransformer();
    transformer.transform(mefHeaderSource, headerElement.getResult());

That does work just fine. It allows me to put one tag only under the header so I get this:

<soapenv:Header xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
	<eai:applicationContext 
		soapenv:actor="http://schemas.xmlsoap.org/soap/actor/next" 
		xmlns:eai="http://www.xxx.co.nz/EAI/UMTS_ICMSAdapter">
		<hdrns:MessageID xmlns:hdrns="http://www.company.com/foo/bar/MyHeader.xsd">1234</hdrns:MessageID>
	</eai:applicationContext>
</soapenv:Header>

But I actually have three tags to add at the level of hdrns:MessageID.
So this is what my code look like now (to produce the above header):

SoapMessage soapMessage = (SoapMessage) message;
SoapHeader soapHeader = soapMessage.getSoapHeader();
SoapHeaderElement headerElement = soapHeader.addHeaderElement(new QName(WebServiceHelper.EAI_NAMESPACE,"applicationContext","eai"));
headerElement.setMustUnderstand(false);
StringBuffer sbHeader = new StringBuffer();
sbHeader.append("<hdrns:MessageID xmlns:hdrns=\"http://www.company.com/foo/bar/MyHeader.xsd\">")
                            .append("1234")
                            .append("</hdrns:MessageID>");
                        
StringSource mefHeaderSource = new StringSource(sbHeader.toString());
Transformer transformer = TransformerFactory.newInstance().newTransformer();
transformer.transform(mefHeaderSource, headerElement.getResult());

If I add another tag to the list in the StringBuffereg:

       <hdrns:MessageID xmlns:hdrns="http://www.xxx.com/x.xsd">1234</hdrns:MessageID>
       <hdrns:TransactionID xmlns:hdrns="http://www.xxx.com/x.xsd">1234</hdrns:TransactionID>

Then I get problems with the XML not being well formed so (understandably) the transform doesn't work (I tried it anyway, just in case).

Is there any way to make a multi-tag element and put it into the header?

I also just tried it with spring-ws-1.5.0 and got the same problem.
It seems to want saxon 9 although xalan 2.7.0 is available so I gave it that.
Also using saaj 1.4 and xerces 2.8.1

I gave up on doing it with a transformer and found this works:

                    SoapMessage soapMessage = (SoapMessage) message;
                    SoapHeader soapHeader = soapMessage.getSoapHeader();
                    DOMResult result = (DOMResult) soapHeader.getResult();
                    Node n = result.getNode();
                    Element applicationContext = n.getOwnerDocument()
                            .createElementNS(WebServiceHelper.EAI_NAMESPACE,
                                    "applicationContext");

                    Element application = n.getOwnerDocument().createElementNS(
                            WebServiceHelper.EAI_NAMESPACE, "application");
                    applicationContext.appendChild(application);
                    application.appendChild(n.getOwnerDocument()
                            .createTextNode(
                                    getWebServiceHeader().getApplication()));

                    Element user = n.getOwnerDocument().createElementNS(
                            WebServiceHelper.EAI_NAMESPACE, "user");
                    user.appendChild(n.getOwnerDocument().createTextNode(
                            getWebServiceHeader().getUser()));
                    applicationContext.appendChild(user);
                    n.appendChild(applicationContext);

Once I noticed that the soapHeader.getResult() returned a DOMResult I realised I had that option (I ought to have noticed earlier, of course).
