Assigning values to SOAP Header

[Pani, Gourav]

hi,

 

i have generated stub classes using WSDL2Java to create a Client object to post to a Web Service.  however, i need to manipulate the SOAP Header in order to send Authorization Information before i execute the transaction. 

 

to accomplish that i just created a org.w3c.dom.Element object and tried to create a SOAPHeaderElement using the MessageElement(org.w3c.dom.Element) constructor. 

 

however, this gives me a null pointer exception, which is puzzling since the org.w3c.dom.Element object called securityInformation is not null.

 

any ideas as to what i might be doing wrong.

 

tia.

 

 

       

    TransactionService serviceLocator = new TransactionServiceLocator();
    Transaction transaction = serviceLocator.getFastWebService();
    TransactionServiceSoapBindingStub stub = (TransactionServiceSoapBindingStub) transaction;

    DocumentBuilder documentBuilder = DocumentBuilderFactory.newInstance().newDocumentBuilder();
    Document document = documentBuilder.newDocument();
    Element securityInformation = document.createElement("SecurityInfo");
    Element authenticationElement = document.createElement("AuthenticationInfo");
    Element authorizationElement = document.createElement("AuthorizationInfo");
    Element fromElement = document.createElement("From");
    Element toElement = document.createElement("To");
       
    authenticationElement.setAttribute("userid", "foo");
    authenticationElement.setAttribute("password", "bar");

 

    fromElement.setAttribute("domain", "brightpoint.com");
    fromElement.setAttribute("system", "BEST");
    toElement.setAttribute("domain", "nextel.com");
    toElement.setAttribute("system", "FAST.FASTWebService.InventoryHandler");
    authorizationElement.appendChild(fromElement);
    authorizationElement.appendChild(toElement);

 

    securityInformation.appendChild(authenticationElement);
    securityInformation.appendChild(authorizationElement);

    
    SOAPHeaderElement securityInfo = new SOAPHeaderElement(securityInformation);
    stub.setHeader(securityInfo);

 

    SenderObject senderObject = new SenderObject();

    stub.updateInventory("Bad Santa", senderObject);
