Java WSDL DHL Classes

Question

I have create Java Classes from the DHL WSDL https://cig.dhl.de/cig-wsdls/com/dpdhl/wsdl/geschaeftskundenversand-api/2.2/geschaeftskundenversand-api-2.2.wsdl.

Now i have all Classes, but no Authentifaction Class. I try this

 GKVAPIServicePortTypeProxy port2 = new GKVAPIServicePortTypeProxy();
        port2.setEndpoint("https://cig.dhl.de/services/sandbox/soap");

     CreateShipmentOrderRequest sh = new CreateShipmentOrderRequest();
        //Setting up shipment;
        .. and so on

        CreateShipmentOrderResponse chr = port2.createShipmentOrder(sh);

But only what i get is, "(401)Authorization Required" How can i set my Authentifiaction ?

Answer 1

Hi I h had fixed the 401 problem with adding of the ssl certificate from DHL to my application truststore. But I have the problem that I missing to add the Authentification block to the request.

<soapenv:Header>
      <cis:Authentification>
         <cis:user>user</cis:user>
         <cis:signature>password</cis:signature>
      </cis:Authentification>
 </soapenv:Header>

My try to adding this block resulting in a 'org.quartz.jobexecutionexception: de.vps.icms.exceptions.icmsscriptingexception: java.lang.noclassdeffounderror: org/apache/axis2/saaj/soapenvelopeimpl'exception.

Some idea what I did wrong? Here the Code: public class WSClient {

   public WSClient() {
        try {
            GKVAPIServicePortType port = prepareService();
            String b = BWIConstants.SYSPARAM_DHL_WS_URL;
            CreateShipmentOrderRequest createShipmentOrderRequest = new CreateShipmentOrderRequest();
            CreateShipmentOrderResponse createShipmentOrderResponse =
                port.createShipmentOrder(createShipmentOrderRequest);
            createShipmentOrderResponse.getStatus();

        } catch (Exception e) {
            e.printStackTrace();

        }

    }

    private GKVAPIServicePortType prepareService() throws MalformedURLException {
        // get Service stub

        String pathToClassFolder = getClass().getResource("/").toString();
        String fullwsdlFilePath = pathToClassFolder + "/" + "geschaeftskundenversand-api-2.2.wsdl";
        URL wsdlLocation = new URL(fullwsdlFilePath);

        GVAPI20De service = new GVAPI20De(wsdlLocation);

        // get Service Port
        GKVAPIServicePortType port = service.getPort(GKVAPIServicePortType.class);

        // overwrite Endpoint
        Map<String, Object> requestContext = ((BindingProvider) port).getRequestContext();
        requestContext.put(BindingProvider.ENDPOINT_ADDRESS_PROPERTY, "https://cig.dhl.de/services/sandbox/soap");

        // overwrite BasicAuth Username and Password
        // requestContext.put(BindingProvider.USERNAME_PROPERTY, cigUser);
        // requestContext.put(BindingProvider.PASSWORD_PROPERTY, cigPass);

        // Add authentication Handler
        Binding binding = ((BindingProvider) port).getBinding();
        List<Handler> handlerChain = binding.getHandlerChain();
        handlerChain.add(
            new AuthenticationHandler(BWIConstants.SYSPARAM_DHL_WS_USER, BWIConstants.SYSPARAM_DHL_WS_SIGNATURE));
        binding.setHandlerChain(handlerChain);

        return port;
    }

Answer 2

Using basic authentication, you would first Base64 encode your username:password - there's online sites that will do it but beware as likely not a good idea to do it if it refers to DHL in anyway, e.g. they could swipe your credentials.
You then get the Request Context of the port, create a map of the headers and add an Authorization header. Finally you add that back to the request context.

Example: Note, I purposely generated bad base64 encoding so you would likely not be able to decode it and see it properly formatted with the "username:password"

        GVAPI20De service1 = new GVAPI20De();

        GKVAPIServicePortType port2 = service1.getGKVAPISOAP11Port0();

        CreateShipmentOrderRequest sh = new CreateShipmentOrderRequest();
        //Setting up shipment;

        Map<String, Object> req_ctx = ((BindingProvider)port2).getRequestContext();

        //you may not need this and can try commenting it out
        req_ctx.put(BindingProvider.ENDPOINT_ADDRESS_PROPERTY, "https://cig.dhl.de/cig-wsdls/com/dpdhl/wsdl/geschaeftskundenversand-api/2.2/geschaeftskundenversand-api-2.2.wsdl");

        //optional timeout
        req_ctx.put("javax.xml.ws.client.connectionTimeout", "60000");

        Map<String, List<String>> headers = new HashMap<String, List<String>>();
        headers.put("Authorization", Collections.singletonList("Basic c3gh567sd4689k11lg=="));

        req_ctx.put(MessageContext.HTTP_REQUEST_HEADERS, headers);

        CreateShipmentOrderResponse chr = port2.createShipmentOrder(sh)
