Call google web service and deal with the return with SOAPMessage

import java.io.FileInputStream;
import java.net.URL;
import javax.xml.namespace.QName;
import javax.xml.soap.MessageFactory;
import javax.xml.soap.SOAPMessage;
import javax.xml.ws.Dispatch;
import javax.xml.ws.Service;
public class GoogleSearch {
  public static void main(String args[]) throws Exception {
    URL url = new URL("http://api.google.ru/GoogleSearch.wsdl");
    QName serviceName = new QName("urn:GoogleSearch", "GoogleSearchService");
    QName portName = new QName("urn:GoogleSearch", "GoogleSearchPort");
    Service service = Service.create(url, serviceName);
    Dispatch<SOAPMessage> dispatch = service.createDispatch(portName, SOAPMessage.class,
        Service.Mode.MESSAGE);
    SOAPMessage request = MessageFactory.newInstance().createMessage(null,
        new FileInputStream("yourGoogleKey.xml"));
    SOAPMessage response = dispatch.invoke(request);
    response.writeTo(System.out);
  }
}

Create SOAP message

    SOAPHeaderElement headerElement = soapHeader.addHeaderElement(soapEnvelope.createName(
        "Signature", "SOAP-SEC", "http://schemas.xmlsoap.org/soap/security/2000-12"));
    SOAPBody soapBody = soapEnvelope.getBody();
    soapBody.addAttribute(soapEnvelope.createName("id", "SOAP-SEC",
        "http://schemas.xmlsoap.org/soap/security/2000-12"), "Body");

    SOAPHeader soapHeader = soapEnvelope.getHeader();
    SOAPHeaderElement headerElement = soapHeader.addHeaderElement(soapEnvelope.createName(
        "Signature", "SOAP-SEC", "http://schemas.xmlsoap.org/soap/security/2000-12"));
    SOAPBody soapBody = soapEnvelope.getBody();
