Question

I am trying to convert a string to JSONObject object using the below code,but i am getting

Exception in thread "main" java.lang.ClassCastException: 
org.json.simple.JSONObject cannot be cast to net.sf.json.JSONObject .

Source:

import net.sf.json.JSONObject;
import org.json.simple.parser.JSONParser;
    public static void run(JSONObject jsonObject) {
        System.out.println("in run--");

    }

    public static void main(String[] args) throws Exception {
        System.out.println("here");
        String json = "{\"task\": \"com.ge.dbt.workers.surveytoexcel.worker.SurveyWorker\",\"prod_id\": 12345,\"survey_id\": 5666,\"person_id\": 18576567,\"req_date\": \"12\12\2012\"}";
        JSONObject jsonObj;
        JSONParser parser = new JSONParser();

        Object obj = parser.parse(json);

        jsonObj = (JSONObject) obj;

        run(jsonObj);
    }

What is wrong here?

Answer 1

You’ve imported JSONObject from the wrong package. Change this line:

import net.sf.json.JSONObject;

to this:

import org.json.simple.JSONObject;
