HttpClient Authentication, Login

So my goal is to enter the forum using httpclient and then post the response to the thread on this forum. I log in to the system in order, but then when I go to the message in the stream, it says that I have not logged in. Any ideas? I tried to create httpClient using cookies, but then I looked at them after I logged in and there was nothing. So I tried using the same httpclient for both calls, but still did not work.

String username, password, threadNum, bumpMessage, bumpTimer;
HttpClient http;

    public void login() throws ClientProtocolException, IOException, NoSuchAlgorithmException
    {

        this.http = HttpClients.createDefault();



        HttpPost httppost = new HttpPost("http://www.sythe.org/login.php?do=login");


        // Request parameters and other properties.
        List<NameValuePair> params = new ArrayList<NameValuePair>(2);
        params.add(new BasicNameValuePair("do", "login"));
        params.add(new BasicNameValuePair("url", ""));
        params.add(new BasicNameValuePair("vb_login_md5password", this.password));
        params.add(new BasicNameValuePair("vb_login_md5password_utf", this.password));
        params.add(new BasicNameValuePair("s", ""));
        params.add(new BasicNameValuePair("vb_login_username", this.username));
        params.add(new BasicNameValuePair("vb_login_password", ""));



        httppost.setEntity(new UrlEncodedFormEntity(params, "UTF-8"));

        //Execute and get the response.
        HttpResponse response = http.execute(httppost);



        HttpEntity entity = response.getEntity();

    }

    public void bump() throws ClientProtocolException, IOException
    {

        HttpPost httppost = new HttpPost("http://www.sythe.org/newreply.php?do=postreply&t=" + this.threadNum);

        // Request parameters and other properties.
        List<NameValuePair> params = new ArrayList<NameValuePair>(2);
        params.add(new BasicNameValuePair("title", ""));
        params.add(new BasicNameValuePair("message", this.bumpMessage));
        params.add(new BasicNameValuePair("wysiwyg", "0"));
        params.add(new BasicNameValuePair("iconid", "0"));
        params.add(new BasicNameValuePair("s", ""));
        params.add(new BasicNameValuePair("posthash", ""));
        params.add(new BasicNameValuePair("poststarttime", ""));
        params.add(new BasicNameValuePair("loggedinuser", ""));
        params.add(new BasicNameValuePair("multiquoteempty", ""));
        params.add(new BasicNameValuePair("sbutton", "Submit Reply"));
        params.add(new BasicNameValuePair("signature", "1"));
        params.add(new BasicNameValuePair("parseurl", "1"));
        params.add(new BasicNameValuePair("emailupdate", "9999"));



        httppost.setEntity(new UrlEncodedFormEntity(params, "UTF-8"));

        //Execute and get the response.
        HttpResponse response = this.http.execute(httppost);

        HttpEntity entity = response.getEntity();

        PrintWriter writer = new PrintWriter("filename.html","UTF-8");

        if (entity != null) {
            InputStream instream = entity.getContent();
            String line;
            BufferedReader br = null;

            try {
                br = new BufferedReader(new InputStreamReader(instream));
                while ((line = br.readLine()) != null) {
                    writer.println(line);
                }
            } finally {
                instream.close();
            }
        }
        writer.close();
    }
}

Edit: I got it in python!
