Java SoapMessage add empty namespace

I am calling third party soap where each element must have a namespace. I am calling from Java to a .NET service. In some elements, I must include "http:/abc.com". Other times, I must include xmlns:"". For example;

<GetYears xmlns="http://example.com">
  <oCar xmlns="">
    <make xmlns="http://example.com">Ford</make>
    <model xmlns="http://example.com">F250</make>
  </oCar>
</GetYears>

I am using javax.xml.soap.*

        MessageFactory messageFactory = MessageFactory.newInstance();
        SOAPMessage soapMessage = messageFactory.createMessage();
        ...
        QName bodyName = new QName("http://example.com", "GetAircraftDueListItems");
        SOAPElement soapBodyElement = soapBody.addBodyElement(bodyName);
        QName qName = new QName("", "oCar");
        SOAPElement carEement = soapBodyElement.addChildElement(qName);

By default, this produces the following output which is rejected by the service because the namespace "" is missing on oCar.

<GetYears xmlns="http://example.com">
  <oCar>
    <make xmlns="http://example.com">Ford</make>
    <model xmlns="http://example.com">F250</make>
  </oCar>
</GetYears>

It appears that an empty namespace is ignored. Is there a way to force the element to include xmlns=""?

Thanks
