How to Pass a BufferedImage? Client - Server

Question

Please Help!
I've been trying to figure out how to send a BufferedImage from my client program to the server program. I'm using a socket to create the connection. The client draws into a BufferedImage and then it is sent to the server to be saved as a JPG file. I've been able to create the image if I do it locally but since a BufferedImage is not serializable I can't do this the same way with the server. So how do I get my BufferedImage from the client to the server in a manner that I can then save it as a JPG on the server? Code examples would be very much appreciated!!!
Thanks!

I guess I'm not understanding what your saying. I just need a way to get what the user draws into a jpg on the server. I have been using sockets and streams but nothing I try really seems to work. Right now I am doing this:
Client:
Socket client = new Socket( InetAddress.getByName( "localhost" ), 5000 );
ObjectOutputStream output = new ObjectOutputStream( client.getOutputStream() );
ObjectInputStream input = new ObjectInputStream( client.getInputStream() );
try {
ByteArrayOutputStream imageOut = new ByteArrayOutputStream();
JPEGImageEncoder encoder = JPEGCodec.createJPEGEncoder( imageOut );
imageOut.flush();
encoder.encode( sig.getImage() );
byte[] image = imageOut.toByteArray();
output.writeObject( image );
Server:
public void runServer() {
ServerSocket server;
Socket connection;
try
server = new ServerSocket( 5000, 100 );
while ( true ) {
connection = server.accept();
output = new ObjectOutputStream(
connection.getOutputStream() );
input = new ObjectInputStream(
connection.getInputStream() );
ObjectOutputStream toFile = new ObjectOutputStream(
new FileOutputStream( f ) );
ByteArrayInputStream inStream =
new ByteArrayInputStream( (byte[]) input.readObject() );
JPEGImageDecoder decoder =
JPEGCodec.createJPEGDecoder( inStream );
BufferedImage sigImage = decoder.decodeAsBufferedImage();
JPEGImageEncoder encoder =
JPEGCodec.createJPEGEncoder( toFile );
encoder.encode( sigImage );
toFile.flush();
output.close();
input.close();
connection.close();
toFile.close();
I imagine I have very ugly looking code here but I've been trying to make something work. My code does create the file but it is not a recognizable JPG file.
