Upload fails using API - java

Authentication went well, I get the auth_token. Then I am using this simple 
code to upload an image: 

<code>
public static void sendFile() throws FileNotFoundException {

        String iFileName = "postcard_template.jpg";
        String lineEnd = "\r\n";
        String twoHyphens = "--";
        String boundary = "*****";
        String Tag = "fSnd";

        fileInputStream = new FileInputStream(iFileName);

        try {

            // Open a HTTP connection to the URL
            HttpURLConnection conn = (HttpURLConnection) new URL(
                    HTTP_UPLOAD_ROUTE_URL).openConnection();

            // Allow Inputs
            conn.setDoInput(true);

            // Allow Outputs
            conn.setDoOutput(true);

            // Don't use a cached copy.
            conn.setUseCaches(false);

            // Use a post method.
            conn.setRequestMethod("POST");

            conn.setRequestProperty("Connection", "Keep-Alive");

            conn.setRequestProperty("Content-Type",
                    "multipart/form-data;boundary=" + boundary);

            DataOutputStream dos = new DataOutputStream(conn.getOutputStream());

            dos.writeBytes(twoHyphens + boundary + lineEnd);
            dos.writeBytes("Content-Disposition: form-data; name=\"api_key\""
                    + lineEnd);
            dos.writeBytes(lineEnd);
            dos.writeBytes(API_KEY);
            dos.writeBytes(lineEnd);
            dos.writeBytes(twoHyphens + boundary + lineEnd);

            dos.writeBytes("Content-Disposition: form-data; name=\"auth_token\""
                    + lineEnd);
            dos.writeBytes(lineEnd);
            dos.writeBytes(AUTH_TOEKN);
            dos.writeBytes(lineEnd);
            dos.writeBytes(twoHyphens + boundary + lineEnd);

            dos.writeBytes("Content-Disposition: form-data; name=\"file\";filename=\""
                    + iFileName + "\"" + lineEnd);
            dos.writeBytes(lineEnd);

            // create a buffer of maximum size
            int bytesAvailable = fileInputStream.available();

            int maxBufferSize = 1024;
            int bufferSize = Math.min(bytesAvailable, maxBufferSize);
            byte[] buffer = new byte[bufferSize];

            // read file and write it into form...
            int bytesRead = fileInputStream.read(buffer, 0, bufferSize);

            while (bytesRead > 0) {
                dos.write(buffer, 0, bufferSize);
                bytesAvailable = fileInputStream.available();
                bufferSize = Math.min(bytesAvailable, maxBufferSize);
                bytesRead = fileInputStream.read(buffer, 0, bufferSize);
            }
            dos.writeBytes(lineEnd);
            dos.writeBytes(twoHyphens + boundary + twoHyphens + lineEnd);

            // close streams
            fileInputStream.close();

            dos.flush();

            InputStream is = conn.getInputStream();

            // retrieve the response from server
            int ch;

            StringBuffer b = new StringBuffer();
            while ((ch = is.read()) != -1) {
                b.append((char) ch);
            }
            String s = b.toString();

            dos.close();
        } catch (MalformedURLException ex) {

        }

        catch (IOException ioe) {

        }
    }</code>
 And I always get the same responce :

<code>
{"success":false,"process_time":372,"result":{"max_filesize":5242880,"space_limi
t":52428800,"space_used":359,"space_left":52428441,"passed":0,"failed":1,"total"
:1,"images":[]},"error":{"error_code":1,"error_message":"One or more file 
uploads have 
failed","error_info":["failed_uploads",{"postcard_template.jpg":{"error_code":1,
"error_message":"Internal error. Unable to upload the file. Please try 
again.","error_info":{"Content-Type":"","filesize":20}}}]}}

</code>

THe last field "filesize" can vary.
