I am trying to create the apex class from WSDL The created class contains error like following

Error: Compile Error: Method does not exist or incorrect signature: WebServiceCallout.invoke(tempuriOrg1.ServiceSoap, tempuriOrg1.HelloWorld_element, MAP<String,PackageTesting.tempuriOrg1.HelloWorldResponse_element>, LIST<String>) at line 22 column 13

Created class

public class tempuriOrg1 {
    public class HelloWorld_element {
        private String[] apex_schema_type_info = new String[]{'http://tempuri.org/','true','false'};
        private String[] field_order_type_info = new String[]{};
    }
    public class ServiceSoap {
        public String endpoint_x = 'http://173.15.158.230/webservice/Service.asmx';
        public Map<String,String> inputHttpHeaders_x;
        public Map<String,String> outputHttpHeaders_x;
        public String clientCertName_x;
        public String clientCert_x;
        public String clientCertPasswd_x;
        public Integer timeout_x;
        private String[] ns_map_type_info = new String[]{'http://tempuri.org/', 'tempuriOrg1'};
        public String HelloWorld() {
            tempuriOrg1.HelloWorld_element request_x = new tempuriOrg1.HelloWorld_element();
            tempuriOrg1.HelloWorldResponse_element response_x;
            Map<String, tempuriOrg1.HelloWorldResponse_element> response_map_x = new Map<String, tempuriOrg1.HelloWorldResponse_element>();
            response_map_x.put('response_x', response_x);
            WebServiceCallout.invoke(
              this,
              request_x,
              response_map_x,
              new String[]{endpoint_x,
              'http://tempuri.org/HelloWorld',
              'http://tempuri.org/',
              'HelloWorld',
              'http://tempuri.org/',
              'HelloWorldResponse',
              'tempuriOrg1.HelloWorldResponse_element'}
            );
            response_x = response_map_x.get('response_x');
            return response_x.HelloWorldResult;
        }
    }
    public class HelloWorldResponse_element {
        public String HelloWorldResult;
        private String[] HelloWorldResult_type_info = new String[]{'HelloWorldResult','http://www.w3.org/2001/XMLSchema','string','0','1','false'};
        private String[] apex_schema_type_info = new String[]{'http://tempuri.org/','true','false'};
        private String[] field_order_type_info = new String[]{'HelloWorldResult'};
    }
}
