Travelport SOAP - СправочникСервис Сервис

Question

Я не очень опытен с SOAP API.

Я пытаюсь разработать API Travelport (GDS) для вызова службы с именем ReferenceLookupService, я могу сделать этот вызов с помощью CURL

    curl --location --request POST 'https://emea.universal-api.pp.travelport.com/B2BGateway/connect/uAPI/SystemService' \
    --header "Authorization: Basic $(echo -n 'Universal API/<USERNAME>:<PASSWORD>' | base64)" \
    --header 'Content-Type: application/xml' \
    --data-raw '<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:util="http://www.travelport.com/schema/util_v49_0" xmlns:com="http://www.travelport.com/schema/common_v49_0">
   <soapenv:Header/>
   <soapenv:Body>
         <util:ReferenceDataRetrieveReq TraceId="doesntmatter-8176" TypeCode="City" xmlns="http://www.travelport.com/schema/util_v49_0">
             <com:BillingPointOfSaleInfo OriginApplication="UAPI"/>
             <util:ReferenceDataSearchModifiers MaxResults="20" ProviderCode="1V"/>
         </util:ReferenceDataRetrieveReq>    
   </soapenv:Body>
</soapenv:Envelope>'
    <SOAP:Envelope xmlns:SOAP="http://schemas.xmlsoap.org/soap/envelope/"><SOAP:Body><sys:PingRsp TraceId="test"

Но в java у меня проблемы. Я уже использовал wsimport для импорта классов Java, и у меня есть класс ReferenceLookupService, который выглядит следующим образом:

/**
 * This class was generated by the JAX-WS RI.
 * JAX-WS RI 2.2.9-b130926.1035
 * Generated source version: 2.2

 */
@WebServiceClient(name = "ReferenceDataLookupService", targetNamespace = "http://www.travelport.com/service/util_v49_0", wsdlLocation = "file:/C:/Users/josem/Desktop/uAPI_WSDLschema_Release-V19.2.0.12/util_v49_0/Util.wsdl")
public class ReferenceDataLookupService
    extends Service
{

    private final static URL REFERENCEDATALOOKUPSERVICE_WSDL_LOCATION;
    private final static WebServiceException REFERENCEDATALOOKUPSERVICE_EXCEPTION;
    private final static QName REFERENCEDATALOOKUPSERVICE_QNAME = new QName("http://www.travelport.com/service/util_v49_0", "ReferenceDataLookupService");

    static {
        URL url = null;
        WebServiceException e = null;
        try {
            url = new URL("file:/C:/Users/josem/Desktop/uAPI_WSDLschema_Release-V19.2.0.12/util_v49_0/Util.wsdl");
        } catch (MalformedURLException ex) {
            e = new WebServiceException(ex);
        }
        REFERENCEDATALOOKUPSERVICE_WSDL_LOCATION = url;
        REFERENCEDATALOOKUPSERVICE_EXCEPTION = e;
    }

    public ReferenceDataLookupService() {
        super(__getWsdlLocation(), REFERENCEDATALOOKUPSERVICE_QNAME);
    }

    public ReferenceDataLookupService(WebServiceFeature... features) {
        super(__getWsdlLocation(), REFERENCEDATALOOKUPSERVICE_QNAME, features);
    }

    public ReferenceDataLookupService(URL wsdlLocation) {
        super(wsdlLocation, REFERENCEDATALOOKUPSERVICE_QNAME);
    }

    public ReferenceDataLookupService(URL wsdlLocation, WebServiceFeature... features) {
        super(wsdlLocation, REFERENCEDATALOOKUPSERVICE_QNAME, features);
    }

    public ReferenceDataLookupService(URL wsdlLocation, QName serviceName) {
        super(wsdlLocation, serviceName);
    }

    public ReferenceDataLookupService(URL wsdlLocation, QName serviceName, WebServiceFeature... features) {
        super(wsdlLocation, serviceName, features);
    }

    /**
     * 
     * @return
     *     returns ReferenceDataLookupPortType
     */
    @WebEndpoint(name = "ReferenceDataLookupPort")
    public ReferenceDataLookupPortType getReferenceDataLookupPort() {
        return super.getPort(new QName("http://www.travelport.com/service/util_v49_0", "ReferenceDataLookupPort"), ReferenceDataLookupPortType.class);
    }

    /**
     * 
     * @param features
     *     A list of {@link WebServiceFeature} to configure on the proxy.  Supported features not in the <code>features</code> parameter will have their default values.
     * @return
     *     returns ReferenceDataLookupPortType
     */
    @WebEndpoint(name = "ReferenceDataLookupPort")
    public ReferenceDataLookupPortType getReferenceDataLookupPort(WebServiceFeature... features) {
        return super.getPort(new QName("http://www.travelport.com/service/util_v49_0", "ReferenceDataLookupPort"), ReferenceDataLookupPortType.class, features);
    }

    private static URL __getWsdlLocation() {
        if (REFERENCEDATALOOKUPSERVICE_EXCEPTION!= null) {
            throw REFERENCEDATALOOKUPSERVICE_EXCEPTION;
        }
        return REFERENCEDATALOOKUPSERVICE_WSDL_LOCATION;
    }

}

Но я понятия не имею, как сделать вышеупомянутый вызов SOAP с помощью этой службы учебный класс. Что я могу попробовать дальше?
