SOAP header authentication for external webservice to use in WebDynpro Java

A bit late in reply, but finally I am able to set the SOAP header in Webdynpro Java. Below are the high level steps I followed:

1) Import the webservice WSDL and create AWS model. While importing, mention the service group name, that will be used in step 5 below.

2) In execute method of component controller write below code (consider above WSDL snippet). Note, that after creating model, proxies are not created for <SOAP:Header> part, but created only for <SOAP:Body> part of WSDL.

Request_ChangePasswordNoOldPassword request_ChangePasswordNoOldPassword = wdContext.nodeRequest_ChangePasswordNoOldPassword().createAndAddRequest_ChangePasswordNoOldPasswordElement().modelObject();
request_ChangePasswordNoOldPassword.wdSetInvocationModifier(new IWDWSInvocationModifier() {   
  
    SOAPHeaderInterface headerInterface = null;
    public void doModifyInvocation(Object port) {
    // TODO Auto-generated method stub
    // Creating the SOAP Header node.   
             DocumentBuilderFactory docBuilderFactory = DocumentBuilderFactory.newInstance();
             docBuilderFactory.setNamespaceAware(false);
             DocumentBuilder docBuilder;
             try {
               docBuilder = docBuilderFactory.newDocumentBuilder();
             } catch (ParserConfigurationException e) {
               // TODO Log the Exception
             wdComponentAPI.getMessageManager().reportException("Error in Executing webservice. Error Description is: " + e.getLocalizedMessage());
               return;
             }
              
              Document soapDoc = docBuilder.newDocument();


               Element AuthHeader = soapDoc.createElementNS("http://www.tmwsystems.com/WebFramework/","web:AuthHeader"); //Set the URI as mentioned in WSDL            
               Element User = soapDoc.createElement("web:User");             
               User.setTextContent(wdContext.currentContextElement().getUser_code());//Set the user
              
               Element Pwd = soapDoc.createElement("web:Pwd");//               
               Pwd.setTextContent(wdContext.currentContextElement().getPwd_code());//Set the password
                              
               AuthHeader.appendChild(User);
               AuthHeader.appendChild(Pwd);
           headerInterface = SOAPHeaderIFactory.getInterface(port);


    // Adds the output SOAP Header to the request.
    try {
    headerInterface.setOutputHeader(null, AuthHeader);   
    } catch (MarshalException e) {
    // TODO Auto-generated catch block
    wdComponentAPI.getMessageManager().reportException("Error in Executing webservice. Error Description is: " + e.getLocalizedMessage());
    e.printStackTrace();
    }


    }
  
    @Override
    public void doModifyAfterInvocation() {
    // TODO Auto-generated method stub


  
    }
    });

3) Deploy the webdynpro DC .

4) Create a provider system. Navigate to NWA->SOA->Technical Configurations->System Connections and click on ‘New’.

5) Create Service Group.Before creating service group, the webdynpro application needs to be deployed on the server.

Go to NWA-> SOA->Application and Scenario Communication->Application Communication

Select the application name (Webdynpro Project) -> Select Service group and click on Edit and select above created Provider system & Save.

Thanks,

Amol.
