not able connect of biz service fo getOrderStatus

[ilaiyaraja_velusamy]

I tried to conect getOrderStatus using the following code from example.

class CallingService{
        public static void main(String[] args) {
               
       
        String output=null;
        String endpoint,inputParam, username, password;
        inputParam= "10001";
        try{
                endpoint = "http://hostname:8080/webtools/control/SOAPService";
                username="admin";
                password="ofbiz";
                Call call = (Call) new Service().createCall();
                call.setTargetEndpointAddress(new URL (endpoint));
                call.setOperationName(new javax.xml.namespace.QName("getOrderStatus"));
                call.addParameter ("orderId", org.apache.axis.Constants.XSD_STRING,javax.xml.rpc.ParameterMode.IN);
                call.addParameter("login.username", org.apache.axis.Constants.XSD_STRING, javax.xml.rpc.ParameterMode.IN);
                call.addParameter("login.password", org.apache.axis.Constants.XSD_STRING, javax.xml.rpc.ParameterMode.IN);
                call.setReturnType(org.apache.axis.Constants.SOAP_STRING);
                Object response = call.invoke(new Object[]{inputParam,username,password});
                output = (String) response;
                try{
                        System.out.println(output);
                }
                catch(Exception e){
                        e.printStackTrace();
                }
        }catch(Exception e){
                e.printStackTrace();
        }
       
        }

Am getting the following error as
