            String res = "";
            String nameSpace = "http://ktews.com/";
            call.setTargetEndpointAddress(new java.net.URL("https://127.0.0.1/KTEWS/KTEWS.asmx"));           
            call.addParameter(new QName(nameSpace, "email"),
                    org.apache.axis.encoding.XMLType.XSD_STRING,
                    javax.xml.rpc.ParameterMode.IN);
            call.addParameter(new QName(nameSpace, "password"),
                    org.apache.axis.encoding.XMLType.XSD_STRING,   
                    javax.xml.rpc.ParameterMode.IN);
            call.addParameter(new QName(nameSpace, "serverUrl"),   
                    org.apache.axis.encoding.XMLType.XSD_STRING,   
                    javax.xml.rpc.ParameterMode.IN);
            call.addParameter(new QName(nameSpace, "amount"),   
                    org.apache.axis.encoding.XMLType.XSD_INT,   
                    javax.xml.rpc.ParameterMode.IN); 
            call.setReturnType(org.apache.axis.Constants.XSD_STRING);
            call.setSOAPActionURI(nameSpace);
            call.setOperationName(new QName(nameSpace, "getUnReadEmail")); 
            res = (String) call.invoke(new Object[] {"test.com", "123456","https://127.0.0.1/EWS/exchange.asmx",5});
            String[] results = res.split("&");
            for(int i = 0 ; i <results.length;i++){
                System.out.println(results[i]);
            }
        } catch (MalformedURLException e) {
            e.printStackTrace();
        } catch (RemoteException e) {
            e.printStackTrace();
        } catch (ServiceException e) {
            e.printStackTrace();
        }
