    Default Socket OutputStream Hanging Up With ImageIO

    I am trying to send a BufferedImage over a socket OutputStream using the ImageIO write method.

    The problem is, the program always hangs up indefinitely on the write method.

    I would assume it's a problem with the socket's stream, but I've tried writing a single byte of data in place of the image and it worked fine.
    So... I'm not really sure.

    Does anyone know how ImageIO.write works? Does it try to write the whole thing at one time? That could cause the socket or server socket to be overloaded...

    That was it! I set the socket buffer sizes a lot higher and it worked. Sorry... this was a waste of a thread. I didn't think of that before though. Only when I was
    writing this...


    [CODE]
    	public void sendImage(BufferedImage bi) {
    		try {
    			ImageIO.write(bi, "jpg", out);
    		} catch (IOException e) {
    			Popup.errorMessage(e.getMessage(), e);
    			e.printStackTrace();
    		}
    	}
    [/CODE]

    [CODE]
    	public BufferedImage readImage() {
    		try {
    			return ImageIO.read(in);
    		} catch (IOException e) {
    			Popup.errorMessage(e.getMessage(), e);
    			e.printStackTrace();
    			return null;
    		}
    	}
    [/CODE]
