KSOAP parameter problem - GlobalWeather service

Hello,
please help me. I am new to KSOAP community, I do not have many experiences
with SOAP at all.
Now I test some SOAP services, many of them succesfully, but this one fail
with "expects parameter'@CountryName".
I mean that I send parameter correctly.
The WSDL is at http://www.webservicex.net/globalweather.asmx?WSDL .
Thank you very much.

Code:
public void readWeather(String country, String city)
{
HttpTransportSE transport = null;
try
{
SoapObject rpc = new SoapObject
("http://www.webservicex.net/globalweather.asmx", "GetWeather");
rpc.addProperty( "CountryName", country);
rpc.addProperty( "CityName", city);
transport = new
HttpTransportSE("http://www.webservicex.net/globalweather.asmx",
"http://www.webserviceX.NET/GetWeather");
transport.debug = true;
SoapObject result = (SoapObject) transport.call (rpc);
for (int i=0; i< result.getPropertyCount(); i++)
t.append( result.getProperty(i).toString() +"\n" );
}
catch (Exception e)
{
t.append( transport.requestDump);
t.append( transport.responseDump);
//e.printStackTrace ();
t.append(e.toString ());
}
}
