Sending object over socket - object contains bufferedimage- Any ideas?

Question

Im sending a object over a socket, an object of the following class:

public class ClientDetail implements Serializable{
public String username;
public String [] capturedText;
public String site;
public BufferedImage screenShot; 
 }

and I am trying to send it using the following:

        ClientDetail cD = new ClientDetail();
        cD.capturedText = mon.getCapturedText();
        cD.username = username;
        cD.site = mon.getWebsite();
        ScreenShot ss = new ScreenShot();
        cD.screenShot = ss.getScreenShot();

        if(mon.isCaptured)
        {
            try{
                output.writeObject(cD);
                output.flush(); 
            }catch(IOException ex){
                System.out.println("\nSomething messed up sending the message!");
            }
        }

This is failing to send. Can you send an object that contains a image over a socket?

What error message did you get? / What was the exception? If you are just swallowing `ex`, then its no wonder that you do not know what goes wrong. — skiwi, Feb 17 '14 at 17:12

I knew it had something to do with the bufferedimage, as u use a different method to write a image over a socket. (Im a a newbie btw..go easy lol) — user3253722, Feb 17 '14 at 17:17
because the bufferedimage isnt serializable i will probably just have to send it separate.. or do u know of a way to make it serializable? — user3253722, Feb 17 '14 at 17:20
Write the BufferedImage to an ByteArrayOutputStream using the method shown in [this answer](http://stackoverflow.com/a/12674109/3080094), remove BufferedImage from ClientDetail and add the byte-array. Byte arrays are Serializable. — vanOekel, Feb 17 '14 at 18:39

Send thing:

ImageIO.write((RenderedImage) image, "png", output);

Receiver thing you know:

ImageIO.read(input);
