Hi Franck,

Finally Made It!  :) 

so here is how to do it.

first, you have to render the form

something like this

responseString = requestGetService(
    " http://localhost:8080/gwt-console-server/rs/form/process/ http://localhost:8080/gwt-console-server/rs/form/process/"
      + "com.sample.evaluation" + "/render", null, false);
  if (responseString.contains("<html>")) {
   responseString = authenticate(address, "krisv", "krisv");
   responseString = requestGetService(
     " http://localhost:8080/gwt-console-server/rs/form/process/ http://localhost:8080/gwt-console-server/rs/form/process/"
       + "com.sample.evaluation" + "/render", null, false);
  }

ok. this will get you the input form

then call the form process complete like this

String address = " http://localhost:8080/gwt-console-server/rs/form/process/com.sample.evaluation/complete http://localhost:8080/gwt-console-server/rs/form/process/com.sample.evaluation/complete";
  String responseString = "";

  Map<String, Object> map = new HashMap<String, Object>();
  map.put("employee", "thomas");
  map.put("reason", "theReason");
  responseString = requestPostMultipartService(address, map);
  if (responseString.contains("<html>")) {
   responseString = authenticate(address, "krisv", "krisv");
   responseString = requestPostMultipartService(address, map);
  }

the result should be:
<div style='font-family:sans-serif; padding:10px;'><h3>Successfully processed input</h3><p/>You can now close this window.</div>

 :) 

and for the functions that I use are:
private String requestPostMultipartService(String url,
   Map<String, Object> parameters) {
  String responseString = "";
  try {
   HttpPost httpPost = new HttpPost(url);
   if (parameters == null)
    parameters = new HashMap<String, Object>();
   MultipartEntity entity = new MultipartEntity(
     HttpMultipartMode.BROWSER_COMPATIBLE);
   Set<String> keys = parameters.keySet();
   for (Iterator<String> keysIterator = keys.iterator(); keysIterator
     .hasNext();) {
    String keyString = keysIterator.next();
    String value = parameters.get(keyString).toString();
    entity.addPart(keyString, new StringBody(value));
   }
   httpPost.setEntity(entity);
   HttpResponse response = httpClient.execute(httpPost);
   responseString = this.getRequestString(response);
  } catch (Exception e) {
  }
  return responseString;
 }

and

private String getRequestString(HttpResponse response) throws Exception {
  InputStreamReader inputStreamReader = null;
  BufferedReader bufferedReader = null;
  String req = "";
  InputStream inputStream = response.getEntity().getContent();
  inputStreamReader = new InputStreamReader(inputStream);
  bufferedReader = new BufferedReader(inputStreamReader);
  StringBuilder stringBuilder = new StringBuilder();
  String line = bufferedReader.readLine();
  while (line != null) {
   stringBuilder.append(line);
   line = bufferedReader.readLine();
  }
  req = stringBuilder.toString();
  return req;
 }

just give it a try and let me know if it works for you  :) 

Regards,
Thomas Setiabudi
