how to implement basic authentication with resttemplate for assembla

[rockmahee]

private void getResponse(LoginBean object) {
    String auth = object.getUsername() + ":" + object.getPassword();
    byte[] encodedAuth = Base64.encodeBase64(auth.getBytes(Charset
            .forName("US-ASCII")));
    String authHeader = "Basic " + new String(encodedAuth);

    RestTemplate restTemplate = new RestTemplate();
    MultiValueMap<String, String> body = new LinkedMultiValueMap<String, String>();
    body.add("client_id", "my_client_id");
    body.add("client_secret", "my_client_secret");
    body.add("grant_type", "client_credentials");
    HttpHeaders headers = new HttpHeaders();
    headers.add("Accept", "application/json");
    headers.set("Authorization", authHeader);
    HttpEntity<?> entity = new HttpEntity<Object>(body, headers);
    ResponseEntity<String> res = restTemplate.exchange(
            "https://api.assembla.com/token?", HttpMethod.POST, entity,
            String.class);
    System.out.println(res.getBody());
    JSONObject json = JSONObject.fromObject(res.getBody());
    String token = json.getString("access_token");
    String url = "https://api.assembla.com/v1/spaces.json";

    HttpClient httpClient = new DefaultHttpClient();
    HttpGet httpGet = new HttpGet(url);

    httpGet.addHeader("Accept", "application/json");
    httpGet.addHeader("Content-type", "application/json");
    httpGet.addHeader("Authorization", "Bearer " + token);
    BufferedReader bufferedReader = null;
    String jsonText = null;

    try {

        // httpPost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
        HttpResponse response = httpClient.execute(httpGet);

        bufferedReader = new BufferedReader(new InputStreamReader(response
                .getEntity().getContent()));

        String line = "";

        while ((line = bufferedReader.readLine()) != null) {
            jsonText = line;
        }
        System.out.println(jsonText);
    } catch (UnsupportedEncodingException e) {
        e.printStackTrace();
    } catch (ClientProtocolException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    } catch (ArrayIndexOutOfBoundsException e) {
        e.printStackTrace();
    }
}

this code have an error: 400 Bad Request when the request for token is posted and due to this with out access token i cant get my response.
