Problema conexão, transferencia e manipulação de arquivo

Programação Java
#41

Yo, consegui fazer uma aplicação com tudo até agora, mas não consigo mandar de volta pro servidor, só consigo receber dele…
pode me ajudar nesta questão que está me tirando de minha paz interior. :x

	public void sendFile() throws IOException {
		ServerSocket servsock = new ServerSocket(13267);
		boolean bool = true;
		while (bool) {
			System.out.println("Waiting...");

			Socket sock = servsock.accept();
			System.out.println("Accepted connection : " + sock);

			File myFile = new File("C:/Publico/teste.xls");
			byte[] mybytearray = new byte[(int) myFile.length()];
			FileInputStream fis = new FileInputStream(myFile);
			BufferedInputStream bis = new BufferedInputStream(fis);
			bis.read(mybytearray, 0, mybytearray.length);
			OutputStream os = sock.getOutputStream();
			System.out.println("Sending...");
			os.write(mybytearray, 0, mybytearray.length);
			os.flush();
			sock.close();

		}
