Cant connect...

I'm trying to acess this site:

http://www.iilab.com:81/mapsservice/mapsservice.asmx?op=GenerateMap

with the following input:

startWayName: Avenida das Igrejas
startDoorNumber: 2
endWayName: Avenida Almirante Reis
endDoorNumber: 6
costID: 1



my java code is:


 public void commandAction(Command c, Displayable d) {
        try {
            // build request string
            String symbol = symbolField.getString();
 

           SoapObject rpc = new SoapObject("http://www.ydreams.
com/MapsService/GenerateMap","GenerateMap");
           	rpc.addProperty("startWayName","avenida das Igrejas");
           	rpc.addProperty("startDoorNumber",new Integer(Integer.parseInt("2"))
);
           	rpc.addProperty("endWayName","avenida almirante reis");
           	rpc.addProperty("endDoorNumber",new Integer(Integer.parseInt("6")));
           	rpc.addProperty("costID",new Integer(Integer.parseInt("1")));
           
            /* 
              SoapObject rpc = new SoapObject("http://tempuri.org/","Add");   
          rpc.addProperty("param1",new Integer(Integer.parseInt("12")));
          rpc.addProperty("param2",new Integer(Integer.parseInt("24")));

		*/
            SoapSerializationEnvelope envelope =
                new SoapSerializationEnvelope(SoapEnvelope.VER11);
		

            envelope.bodyOut = rpc;
            System.out.println(envelope.bodyOut.toString());           

            resultItem.setLabel(symbol);

		HttpTransport ht = new HttpTransport("http://www.iilab.com:
81/mapsservice/mapsservice.asmx");
           // HttpTransport ht = new HttpTransport("http://localhost:81/NewFile.
asmx");
             ht.debug = true;
             
             try {
             	System.out.println("trying to connect");
             
                ht.call("http://www.ydreams.com/MapsService/GenerateMap",
envelope);
                //ht.call("http://tempuri.org/Add",envelope);
                System.out.println(envelope.bodyIn.toString());
                
                System.out.println(envelope.toString());
                System.err.println (ht.requestDump);  
                System.err.println (ht.responseDump);  
              
             }
             catch (Exception e) {
                e.printStackTrace();
                System.err.println (ht.requestDump);  
                System.err.println (ht.responseDump);  
             }

            resultItem.setText("" + envelope.getResult());

        }
        catch (Exception e) {
            e.printStackTrace();
            resultItem.setLabel("Error:");
            resultItem.setText(e.toString());
        }
    }





BUT I GOT this error:

ault{faultcode=soap:Client; faultstring=Server was unable to read request. --> 
There is an error in XML document (1, 233). --> <GenerateMap xmlns='http:
//www.ydreams.com/MapsService/GenerateMap'> was not expected.; detail=null; }
