http response code 400 in httpurlconnection's getinputstream

[mark goking]

hi. im baffled why the con.getInputstream() returns an http response code of 400. here is the code

  
    AudioFormat format = MyDefaulAudioFormat();

    AudioInputStream ais = null;
    try {
        String audioURL  =URLS.getAudioURL( currentAnnotationId);
        URL pservice = new URL(audioURL);
        HttpURLConnection conn = (HttpURLConnection) pservice.openConnection();
        conn.setDoOutput(true);
        conn.setDoInput(true);

        int byteLength = 4096;
        OutputStream outStream = conn.getOutputStream();
        //add the byte size in buffered output stream
        BufferedOutputStream bos = new BufferedOutputStream(conn.getOutputStream(), byteLength);
        ByteArrayInputStream bais = new ByteArrayInputStream(baos.toByteArray());

        int numberBytesRead = 0;
        byte[] byteArray = new byte[byteLength];
        while (numberBytesRead != -1) {
            numberBytesRead = bais.read(byteArray, 0, byteLength);
            if (numberBytesRead != -1) {
                bos.write(byteArray, 0, numberBytesRead);
            }
        }

        bos.flush();
        bos.close();
        bais.close();

        conn.getInputStream().close(); <<< ERROR HERE

    } catch (MalformedURLException ex) {
        Logger.getLogger(Mine.class.getName()).log(Level.SEVERE, null, ex);
    } catch (IOException ex) {
        Logger.getLogger(Mine.class.getName()).log(Level.SEVERE, null, ex);
    } catch (Exception ex) {
        Logger.getLogger(Mine.class.getName()).log(Level.SEVERE, null, ex);
    } finally {
    }
  

any ideas? thanks

A HTTP 400 error code is a "Bad Request". Can you reach the site with a browser? I see you are attempting to upload some data. Is there a service on the server side that can receive data?

[mark goking]

yes. actually it works if the file is small. the problem arises when the file's big

[Joe Ess]

What size file breaks it? Is there a limitation on the server?

[mark goking]

hey joe i will let you know. my friend who did the server side module modified the code to accept an xml with base64 rather than sending the inputstream byte array when http posting
