java.lang.IllegalStateException: No unmarshaller registered. Check configuration of WebServiceTemplate

Question

When I send a SOAP request to the server it returns following error. I am not sure how I can configure unmarshaller, I am going to send SOAP requests to multiple webservices. WSDL is here.

I visited following pages but could not find a solution yet. 1,2,3

Code to send request

import javax.xml.soap.MessageFactory;
import javax.xml.soap.SOAPConstants;

import org.springframework.oxm.jaxb.Jaxb2Marshaller;
import org.springframework.stereotype.Service;
import org.springframework.web.client.RestClientException;
import org.springframework.web.client.RestTemplate;
import org.springframework.ws.client.core.WebServiceTemplate;
import org.springframework.ws.soap.saaj.SaajSoapMessageFactory;
......
    // populate searchFlights and other classes to create request
    try {
        SaajSoapMessageFactory messageFactory = new SaajSoapMessageFactory(
                MessageFactory.newInstance());
        messageFactory.afterPropertiesSet();

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

        marshaller.setContextPath("com.myproject.flights.wegolo");
        marshaller.afterPropertiesSet();

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



            Response response = (Response) webServiceTemplate
                            .marshalSendAndReceive(   <<< ERROR is on this line
                                 "http://www5v80.elsyarres.net/service.asmx",
                                  searchFlights,
                                  new WebServiceMessageCallback() {
                                     public void doWithMessage(WebServiceMessage message) 
                                        {

                     ((SoapMessage)message).setSoapAction("http://www5v80.elsyarres.net/searchFlights");
                                        }
                                   }
                               );
            Response msg = (Response) response;
            System.err.println("Wegolo >>>"
                    + msg.getFlights().getFlight().size());
        } catch (Exception s) {
            s.printStackTrace();
        }

Solution

It seems that you didn't set the unmarshaller on your webServiceTemplate.

webServiceTemplate.setMarshaller(marshaller);
webServiceTemplate.setUnmarshaller(marshaller);
