Make sure your content type is application/json.


   HttpClient client = new HttpClient();
      client.getState().setCredentials(
            new AuthScope("localhost", 8080, "Alfresco"),
            new UsernamePasswordCredentials("admin", "admin"));
      String uid = "51920ee3-14c0-4477-a637-ab82a0d8df70";
      String apiurl = "http://localhost:8080/alfresco/service/api/node/workspace/SpacesStore/'+uid+'/comments";
      PostMethod post = new PostMethod(apiurl);
      try {
         JSONObject site = new JSONObject();
         site.put("title", "this is a test title");
         site.put("content", "this is a test content");

         System.out.println(site.toString());
         post.setDoAuthentication(true);
         post.setRequestHeader("Content-Type", "application/json");
         post.setRequestEntity(new StringRequestEntity(site.toString(),
               "application/json", "UTF-8"));

         int status = client.executeMethod(post);
         if (status != HttpStatus.SC_OK) {
            System.err.println("Method failed: " + post.getStatusLine());
         }
         String resultString = post.getResponseBodyAsString();
         System.out.println(resultString);
      } catch (Exception e) {
         e.printStackTrace();
      } finally {
         post.releaseConnection();
      }

Thanks for this useful example!

Just one last question: is it possible to invoke the POST using a ticket (alf_ticket or ticket, gained invoking http://localhost:8080/alfresco/service/api/login?u=admin&pw=admin) instead of basic authentication?

Thanks again

PS Solved:

String apiurl = "http://localhost:8080/alfresco/service/api/node/workspace/SpacesStore/'+uid+'/comments?alf_ticket=TICKET_699c56c2b5149a77b2c6ecd47cdfc5998444a77d";‍
