How to use the same channel to send a file and messages to the server

Question

I'm trying to develop a simple program that will send and receive files from the server and in the same time I need to communicate with the server through the messages
I'm using TCP Socket
my problem is
I have only one channel
so, I have no option, either I can use it for sending the file itself or sending the message .. but not both !
my question is : How can I use the same channel for sending and receiving (file & message)
I would appreciate for any clue or hint
best

Thanks for reply
yes, that what I'm thinking to do
but, in case of sending binary file, if I attached a flag on its header, will it corrupt the file ?
bestThe other end would of course need to decode the messages that you get, and only write the "data" part to the file.Thanks
I'm gonna try to hard-code what you suggest and i will post what happen with me here
even though I'm not sure how can I add header to a binary file and remove it from the file at other end. (coz I read it as stream and send as array without touching its contents)
this how I'm sending the file
ConnSocket = CSocket.accept();
ToClient = new DataOutputStream(ConnSocket.getOutputStream());
File myFile = new File("abc.jpg");
FileInputStream myFileInStream = new FileInputStream(myFile);
BufferedInputStream mybuffInStream = new BufferedInputStream(myFileInStream);
myBytArray = new byte[(int) myFile.length()];
mybuffInStream.read(myBytArray, 0, myBytArray.length);
ToClient.write(myBytArray, 0, myBytArray.length);
ToClient.flush();
myFileInStream.close();best
