Setting a custom HTTP header dynamically with Spring-WS client

Question

How do you set a custom HTTP header (not SOAP header) dynamically on the client side when using Spring-WS?

Answer 1

The following fragment has been tested with Spring 4.0. It appends a WebServiceMessageCallback to a org.springframework.ws.client.core.WebServiceTemplate

final String DYNAMICVALUE = "myDynamo";

WebServiceMessageCallback wsCallback = new WebServiceMessageCallback() {           
       public void doWithMessage(WebServiceMessage message) {
            try {
                        SoapMessage soapMessage = (SoapMessage)message;
                        SoapHeader header = soapMessage.getSoapHeader();
                        header.addAttribute(new QName("myHeaderElement"), DYNAMICVALUE);                        
            } catch (Exception e) {
                        e.printStackTrace();
            }
       }
};

JAXBElement response = (JAXBElement)
        wsTemplate.marshalSendAndReceive(MyWsOP, wsCallback);
