How to send JSON object from POSTMAN to Restful webservices

Question

I am trying to send JSON from POSTMAN to a RESTful web service. I followed this tutorial URL to send JSON through POSTMAN.

My URL:

HTTP: // local: 8080 / MyWebservice / rest / dataInsert / insert

My service method:

@POST
    @Path("/insert")
    @Consumes(MediaType.APPLICATION_JSON)
    public String insertData(JSONObject jsonlist) throws UnknownHostException;

My impl:

@Override
    public String insertData(JSONObject jsonlist) throws UnknownHostException {
        System.out.println(jsonlist);
        insertDataDao.insertData(jsonlist);
        return "SUCCESS";
    }

My DAO:

public  String insertData(JSONObject jsonlist) throws UnknownHostException{
        System.out.println(jsonlist);
        MongoConnection mongoconnection = new MongoConnection();
        MongoClient mongoclient = mongoconnection.getMongoClient();

        MongoDatabase db = mongoclient.getDatabase("mydb");
        MongoCollection<Document> col = db.getCollection("col");

        String jsonString = jsonlist.toString();
        System.out.println(jsonString);

        Document doc = Document.parse(jsonString);
         col.insertOne(doc);
        System.out.println("Inserted Successfully !!!");
        return "SUCCESS";

    }

But I encounter the following exception:

JBWEB000236: Servlet.service () for the CXFServlet servlet generated an exception: java.lang.NoSuchMethodError: javax.ws.rs.InternalServerErrorException.validate (Ljavax / ws / rs / core / Response; status / core / Response; Lj $ $;) Ljavax / WS / RS / core / response;

I can not solve this problem. Can someone please help me regarding this ...

POSTMAN V5.2.0

I had the same problem that was solved by importing the dependency jersey.jsonand adding it toweb.xml

<init-param>
        <param-name>com.sun.jersey.api.json.POJOMappingFeature</param-name>
        <param-value>true</param-value>
    </init-param>
