I want to send an image from a J2ME client to a Servlet.

I am able to get a byte array of the image and send it using HTTP POST.

conn = (HttpConnection) Connector.open(url, Connector.READ_WRITE, true);
conn.setRequestMethod(HttpConnection.POST);
conn.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
os.write(bytes, 0, bytes.length); // bytes = byte array of image

This is the Servlet code:

String line;
BufferedReader r1 = new BufferedReader(new InputStreamReader(in));
while ((line = r1.readLine()) != null) {
    System.out.println("line=" + line);
    buf.append(line);
}
String s = buf.toString();
byte[] img_byte = s.getBytes();

But the problem I found is, when I send bytes from the J2ME client, some bytes are lost. Their values are 0A and 0D hex. Exactly, the Carriage Return and Line Feed.

Thus, either POST method or readLine() are not able to accept 0A and 0D values.

Any one have any idea how to do this, or how to use any another method?
