How to send JSON Object from POSTMAN to Restful webservices
<p>I'm trying to send json from POSTMAN to RESTful webservice. I had followed this tutorial <a href="http://docs.brightcove.com/en/perform/player-management/guides/postman.html" rel="noreferrer">url</a> for sending json through POSTMAN.</p>

<p><strong>My URL :</strong></p>

<p><a href="http://localhost:8080/myWebService/rest/dataInsert/insert" rel="noreferrer">http://localhost:8080/myWebService/rest/dataInsert/insert</a></p>

<p><strong>My Service method:</strong></p>

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

<p><strong>My Impl:</strong></p>

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

<p><strong>My DAO:</strong></p>

<pre><code>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&lt;Document&gt; 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";

    }
</code></pre>

<p>But I'm facing the below Exception:</p>

<blockquote>
  <p>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;</p>
</blockquote>

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