port and service names

Hi there, 
I'm trying to run a stockqoute service found at: http://www.nexus6studio.org/Services/StockQoute.asmx. it.
Would anyone know what I should be filling in for the service and port name variables below?
(The main error I get when I run my client is: "Server did not recognize the value of HTTP Header SOAPAction: .").
Here's the short piece of client code:


import javax.xml.rpc.*;
import javax.xml.namespace.QName;

public class next{
    private static String endpoint = "http://www.nexus6studio.org/Services/StockQoute.asmx";
    private static String qnameService = "GetQuickQuote";
    private static String qnamePort = "";

    private static String BODY_NAMESPACE_VALUE = "";
    private static String ENCODING_STYLE_PROPERTY = "javax.xml.rpc.encodingstyle.namespace.uri";
    private static String NS_XSD = "http://www.w3.org/2001/XMLSchema";
    private static String URI_ENCODING = "http://schemas.xmlsoap.org/soap/encoding/";

    public static void main(String args[])throws Exception{
        try{

            ServiceFactory factory = ServiceFactory.newInstance();
            Service service = factory.createService(new QName(qnameService));
            QName port = new QName(qnamePort);

            Call call = service.createCall(port);
            call.setTargetEndpointAddress(endpoint);

            call.setProperty(Call.SOAPACTION_USE_PROPERTY, new Boolean(true));
            call.setProperty(Call.SOAPACTION_URI_PROPERTY,"");
            call.setProperty(ENCODING_STYLE_PROPERTY, URI_ENCODING);

            QName QNAME_TYPE_STRING = new QName(NS_XSD,"string");
            call.setReturnType(QNAME_TYPE_STRING);

            call.setOperationName(new QName(BODY_NAMESPACE_VALUE, "getQuickQuote"));///
            call.addParameter("Ticker", QNAME_TYPE_STRING, ParameterMode.IN);///
            String[] params = { "MSFT" };///

            String result = (String)call.invoke(params);
            System.out.println(result);
        }
        catch(Exception e){
            e.printStackTrace();
        }
    }
}
