I tried to generate some lists from existing SOAP webservice. But the problem is that, I always getting null value when tried to generate it.
Maybe someone can comment why this problem is happening to me?
Thanks!

Steps which I am doing:

I have generated wsdl from WSDL_link

Generated wsdl files with plugin:

<plugin>
 <groupId>org.codehaus.mojo</groupId>
 <artifactId>jaxws-maven-plugin</artifactId>
 <version>2.5</version>
 <executions>
 <execution>
 <goals>
 <goal>wsimport</goal>
 </goals>
 <!-- Following configuration will pass $project.basedir/src/remote-xjc/bindings.xjc 
 and $project.basedir/src/jaxws/bindings-default.xjc to wsimport. -->
 <configuration>
 <wsdlUrls>
 <wsdlUrl>$project.basedir/src/main/resources/wsdl/FxRates_12.wsdl</wsdlUrl>
 </wsdlUrls>
 </configuration>
 </execution>
 </executions>
 </plugin>

I used this plugin, because other plugins give me always errors.
And tried to call it with:

@RestController
public class GetRatesController 
private static final String soapEndpointUrl = "http://old.lb.lt/webservices/FxRates/FxRates.asmx";
private static final String soapAction = "http://www.lb.lt/WebServices/FxRates/getCurrencyList";
@RequestMapping(value = "/get", method = RequestMethod.GET, produces = "application/xml")
public ResponseEntity<GetCurrencyListResponse> getIndexView() 
 GetCurrencyListResponse response = new GetCurrencyListResponse();
 try 
 // Create SOAP Connection
 SOAPConnectionFactory soapConnectionFactory = SOAPConnectionFactory.newInstance();
 SOAPConnection soapConnection = soapConnectionFactory.createConnection();
 // Send SOAP Message to SOAP Server
 GetCurrencyList getCurrencyList = new GetCurrencyList();
 SOAPMessage soapResponse = soapConnection.call(createSOAPRequest(soapAction, getCurrencyList), soapEndpointUrl);
 JAXBContext jaxbContext = JAXBContext.newInstance(GetCurrencyListResponse.class);
 Unmarshaller unmarshaller = jaxbContext.createUnmarshaller();
 response = (GetCurrencyListResponse) unmarshaller.unmarshal(soapResponse.getSOAPBody().extractContentAsDocument()); 
 catch (Exception e) 
 System.err.println("nError occurred while sending SOAP Request to Server!nMake sure you have the correct endpoint URL and SOAPAction!n");
 e.printStackTrace();
 
 System.out.println(response.getGetCurrencyListResult().getContent());
 return new ResponseEntity<>(response, HttpStatus.OK);

private static <T> SOAPMessage createSOAPRequest(String soapAction, T requestClass) throws Exception 
 MessageFactory messageFactory = MessageFactory.newInstance();
 SOAPMessage soapMessage = messageFactory.createMessage();
 createSoapEnvelope(soapMessage, requestClass);
 MimeHeaders headers = soapMessage.getMimeHeaders();
 headers.addHeader("SOAPAction", soapAction);
 soapMessage.saveChanges();
 return soapMessage;

private static <T> void createSoapEnvelope(SOAPMessage soapMessage, T requestClass) throws SOAPException, JAXBException 
 SOAPPart soapPart = soapMessage.getSOAPPart();
 SOAPEnvelope envelope = soapPart.getEnvelope();
 JAXBContext jaxbContext = JAXBContext.newInstance(requestClass.getClass());
 Marshaller jaxbMarshaller = jaxbContext.createMarshaller();
 jaxbMarshaller.setProperty(Marshaller.JAXB_FRAGMENT, Boolean.TRUE);
 StringWriter sw = new StringWriter();
 // SOAP Body
 SOAPBody soapBody = envelope.getBody();
 jaxbMarshaller.marshal(requestClass, sw);
 System.out.println(sw.toString());
 soapBody.addTextNode(sw.toString());

But the result I am getting is null.
Which part is wrong? How to get the currency list, which service should return?
XML of currency list service: XML
