title: Querying a JSON REST Service with POSTMAN/Rest Client
body: <p>I have a simple RESTLET Service which returns a JSON representation, as shown below:</p>
  
  <pre><code>@Override
      @Post("json")
  public Representation helloWorld() {
      Representation representation = new JacksonRepresentation&lt;Hello&gt;(new Hello("Hello World"));
      representation.setMediaType(MediaType.APPLICATION_JSON);
      representation.
      return representation;
  }
  </code></pre>
  
  <p>When I query this using cURL I get the response as expected:</p>
  
  <pre><code>{"greeting":"Hello World"}
  </code></pre>
  
  <p>However I do not get a response when I use the browser or POSTMAN or indeed any other web REST client. I get the response 'Could not get any response' from POSTMAN.</p>
  
  <p>The preview of the POSTMAN request is: </p>
  
  <pre><code>POST /testingrestlet/hello HTTP/1.1
  Host: 127.0.0.1:6000
  Content-Type: application/json
  Cache-Control: no-cache
  Postman-Token: 5141cd87-505c-e813-0045-3b7f4aa54144
  </code></pre>
  
  <p>I would at least have expected a REST client such as POSTMAN to work, or am I missing something?</p>
  
  <p>Any help appreciated.</p>
  
  <p>Regards</p>
