I am trying to send a request to a SOAP webservice. I read this tutorial and prepared the following code. However, I am going to send different requests to multiple SOAP webservices, whereas the tutorial focused on one request. How can I send SOAP request using ?WebserviceTemplate

WebServiceTemplate

    SoapMessage soapMsg = new SoapMessage();
    soapMsg.setUsername("Requester");
    soapMsg.setPassword("Pass");
    soapMsg.setLanguageCode("EN");
    Request request = new Request();
    request.setDeparture("FDH");
    request.setDestination("HAM");
    Date date = new Date();
    SimpleDateFormat frm2 = new SimpleDateFormat("yyyy-MM-dd");
    request.setDepartureDate(frm2.parse(frm2.format(date)));
    request.setNumADT(1);
    request.setNumCHD(0);
    request.setNumInf(0);
    request.setCurrencyCode("EUR");
    request.setWaitForResult(true);
    request.setNearByDepartures(true);
    request.setNearByDestinations(true);
    request.setRronly(false);
    request.setMetaSearch(false);
    soapMsg.setRequest(request);
    WebServiceTemplate webServiceTemplate = new WebServiceTemplate().  //how to create object and send request!
    Object response = webServiceTemplate.marshalSendAndReceive(
            "https://aaa5.elsyarres.net", soapMsg);
    Response msg = (Response) response;
    System.err.println("size of results of wogolo:"
            + msg.getFlights().getFlight().size());

You can use following code, you do not need to define anything in xml file.

  try {
            SaajSoapMessageFactory messageFactory = new SaajSoapMessageFactory(
                    MessageFactory.newInstance());
            messageFactory.afterPropertiesSet();

            WebServiceTemplate webServiceTemplate = new WebServiceTemplate(
                    messageFactory);
            Jaxb2Marshaller marshaller = new Jaxb2Marshaller();

            marshaller.setContextPath("PACKAGE");
            marshaller.afterPropertiesSet();

            webServiceTemplate.setMarshaller(marshaller);
            webServiceTemplate.afterPropertiesSet();

            Response response = (Response) webServiceTemplate
                    .marshalSendAndReceive(
                            "address",
                            searchFlights);

            Response msg = (Response) response;
        } catch (Exception s) {
            s.printStackTrace();
        }

To send different SOAP requests to different SOAP services, you just need to make your WebServiceTemplate aware of all requests and responses it will have to process.

Create a Java class for each request and response like so:

package models;
import javax.xml.bind.annotation.XmlRootElement;
import java.io.Serializable;

@XmlRootElement
public class FlyRequest implements Serializable {

    private boolean nearByDeparture;

    public FlyRequest() {}

    public boolean isNearByDeparture() {
        return nearByDeparture;
    }

    public void setNearByDeparture(boolean nearByDeparture) {
        this.nearByDeparture = nearByDeparture;
    }
}

(The @XmlRootElement is because we use JAXB marshaller below; see Jaxb reference for more info).

The setup of the template is done for example like so:

    SaajSoapMessageFactory messageFactory = new SaajSoapMessageFactory(MessageFactory.newInstance());
    messageFactory.afterPropertiesSet();

    WebServiceTemplate webServiceTemplate = new WebServiceTemplate(messageFactory);
    Jaxb2Marshaller marshaller = new Jaxb2Marshaller();
    marshaller.setContextPath("models");
    marshaller.afterPropertiesSet();

    webServiceTemplate.setMarshaller(marshaller);
    webServiceTemplate.afterPropertiesSet();

"models" is the name of the package where the Request/Responses classes are, so that jaxb can find them.

Then you just instantiate the request of the class you want to perform the call, like so:

    // call fly service:
    FlyRequest flyRequest = new FlyRequest();
    flyRequest.setNearByDeparture(false);
    Object flyResponse = webServiceTemplate.marshalSendAndReceive("https://example.net/fly", flyRequest);

    // call purchase service:
    PurchaseRequest purchaseRequest = new PurchaseRequest();
    purchaseRequest.setPrice(100);
    Object purchaseResponse = webServiceTemplate.marshalSendAndReceive("https://example.net/purchase", purchaseRequest);

Similarly, you can cast the response objects into your JAXB classes defined above.
