[httpclient] get vs post

[Erwan Baynaud]

Does somebody can tell me why this code works :

        HttpClient client = new HttpClient();
       PostMethod post = new
PostMethod("http://127.0.0.1:8080/interactivity/servlet/VoteResultsServlet";);
       NameValuePair[] data = {
                new NameValuePair("ID_USER","1"),
                new NameValuePair("ID_INTERACTIVITY","1")
       };
       post.setQueryString(data);
                client.executeMethod(post);
       String response = new
String(post.getResponseBodyAsString().getBytes("8859_1"));
       System.out.println(response);
       post.releaseConnection();
                }



And this one not :

        HttpClient client = new HttpClient();
       GetMethod post = new
GetMethod("http://127.0.0.1:8080/interactivity/servlet/VoteResultsServlet";);
       NameValuePair[] data = {
                new NameValuePair("ID_USER","1"),
                new NameValuePair("ID_INTERACTIVITY","1")
       };
       post.setQueryString(data);
                client.executeMethod(post);
       String response = new
String(post.getResponseBodyAsString().getBytes("8859_1"));
       System.out.println(response);
       post.releaseConnection();
                }



I would like to use a POST method but only the GET one works.

Thank you.
