下面是我在网上找的调用方法public static void getAxisService(){
        Service service = new Service();
        Call call = null;
        String result = null;
        try {
            call = (Call)service.createCall();
        } catch (ServiceException e) {
            e.printStackTrace();
        }
        try {
        call.setTargetEndpointAddress("http://teacode.xhnw.com:8080/getteafarmer.asmx");
        call.setOperationName("GetTeaFarmerByCode");
        call.setUseSOAPAction(true);
        call.setSOAPActionURI("http://teacode.xhnw.com:8080/GetTeaFarmerByCode");
            result = (String)call.invoke(new Object[]{"1461754","457898121455",""});
        } catch (RemoteException e) {
            e.printStackTrace();
        }
        System.out.println(result);
}请帮我看看  里面的几个参数该怎么写？ 万分感激！
