How to send JSON Object from POSTMAN to Restful webservices

Question

I'm trying to send json from POSTMAN to RESTful webservice. I had followed this tutorial url for sending json through POSTMAN.

My URL :

http://localhost: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'm facing the below Exception:

JBWEB000236: Servlet.service() for servlet CXFServlet threw exception: java.lang.NoSuchMethodError: javax.ws.rs.InternalServerErrorException.validate(Ljavax/ws/rs/core/Response;Ljavax/ws/rs/core/Response$Status;)Ljavax/ws/rs/core/Response;

I'm unable to fix this issue. Can anyone please help me out regarding this ...

Nothing wrong with the Postman call. can you add some code of the method , where you are making the request. And that methods return type should be Response. @dev777 — Istiak Morsalin, Aug 16 '16 at 10:39
You compilation time Jax-rs implementation is different compared to application runtime. Check which version of CXF is used by your JBOSS server. — ravthiru, Aug 16 '16 at 11:50

Step 1: open postman type your api url and select post type.

Step 2: goto Headers button type("Content-Type") first input box and type "application/json" in second input box it gives auto-complete suggestion

Step 3: goto Body button and choose raw radio button and choose JSON (application/json) in drop down in same raw right side.

Step 4: type your json like student object

{
  "name": "dummy",
  "marks": "26"
}

check the attached sample example image

POSTMAN V5.2.0 Testing

Steps:

Paste above JSON data by click BODY -> raw -> JSON (application/json)

I had the same problem which was solved by importing the jersey.json dependency first and then adding this in web.xml

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