sending a snapshot array byte to server

[irene1986]

hi all

I am trying to send a snapshot array byte from a MIDlet to a pc. My problem is that i cannot receive the array byte completely.

my shapshot is taken using this code:

byte[] image = videoCon.getSnapshot(null);

my outputstream to send the array byte looks like:

stream = (StreamConnection)Connector.open(url);
  OutputStream out = stream.openOutputStream();
  out.write(image);  
  out.close();
  stream.close();

and my server has the following to receive the stream:

ByteArrayOutputStream baos = new ByteArrayOutputStream();
System.out.println("3:"+bis);
byte b;
while ((b=(byte)bis.read())!= -1){
	System.out.println(b);
	baos.write(b);
}
System.out.println(b);
System.out.println("writing to file");
byte[]imgByte = baos.toByteArray();

where bis is the bufferedinputstream

i know the code works since i have tried sending an array comprising only of strings, whatever the length, and i can receive it all.
but for the case of the array of bytes, i do not get the whole array, only a very small part of it.

my objective is taking a picture from a midlet, and sending that picture to a server and save somewhere.

if anyone got an idea of whats wrong or another way of doing this, i would be really greatful
thanks in advance

Hey,

Try to split it into a payload of 250bytes and send it.

hello, thanks for your reply

i have no experience with payload, i am currently searching for some material on it, to try what you just said...

if u have any links or materials on this please let me know

thanks in advance

1)allocate a buffer of 250 bytes (for example, just keep it small)
2) //DO THAT IN A SEND THREAD

  n_bytes_sent = 0;
  while (n_bytes_sent< imagesize)
    bytes_left = imagesize - n_bytes_sent;
    if(bytes_left>=250)
       n_2_copy = 250;
    else
       n_2_copy = bytes_left;
   
    copy(my_buffer, from_image_bytes_array, n_2_copy, n_bytes_sent);
    send(my_buffer);
    n_bytes_sent += 250;
    sleep(200);
