Spring jaxb WebServiceGatewaySupport implementation java.lang.IllegalArgumentException - spring

Question

I'm working in jaxb with Spring, trying to write a custom unmarshalling process using WebServiceGatewaySupport.
My class is below. The problem is with response, when I call the following method
getWebServiceTemplate().sendSourceAndReceiveToResult
It crashes with message "java.lang.IllegalArgumentException: 'uri' must not be empty". It seems like even though I am using StringResult, it is trying to parse xml and finding a xml/soap response error.
public class WUResultGateway extends WebServiceGatewaySupport{
private WebServiceTemplate webServiceTemplate;
private SourceExtractor ratingResponseExtractor = new WUResponseExtractor();
public WUResultGateway(WebServiceTemplate webServiceTemplate){
this.webServiceTemplate = webServiceTemplate;
}
private Source marshall( SendRDCResults results ) throws IOException{
StringResult resp = new StringResult();
Marshaller marshaller = webServiceTemplate.getMarshaller();
marshaller.marshal( results, resp );
return new ResourceSource( new ByteArrayResource( resp.toString().getBytes() ) );
}
public Object wuResponse( SendRDCResults results) throws IOException{
//StringSource source = new StringSource();
Result result = new StreamResult();
StringResult strResult = new StringResult();
boolean flag = getWebServiceTemplate().sendSourceAndReceiveToResult( marshall( results ), strResult );
return result;
}
}
Without making any change to the response from the server, I want to get values in s String or simple xml format without errors. Can anyone help?

Answer 1

setDefaultUri(webServiceTemplate.getDefaultUri());
finally looks as follows
public Object wuResponse( SendRDCResults results) throws IOException{
//StringSource source = new StringSource();
Result result = new StreamResult();
StringResult strResult = new StringResult();
setDefaultUri(webServiceTemplate.getDefaultUri());
boolean flag = getWebServiceTemplate().sendSourceAndReceiveToResult( marshall( results ), strResult );
return result;
}
