EOFException randomly

[elamre]

Hello all,

I'm trying to make my own dropbox kind of program. Just for the funs of it, and extreme customisation.
Now i've got a small problem while trying to send the file info in advance. Mostly the first time i connect everything goes just fine.
But as soon as another client connects i get the error:

java.io.EOFException
	at java.io.DataInputStream.readInt(Unknown Source)
	at FileInfo.read(FileInfo.java:38)
	at FileSendRecieve.recieveFile(FileSendRecieve.java:30)
	at Client.run(Client.java:24)
	at java.lang.Thread.run(Unknown Source)

I've been googling around this error, but find it quite hard to find a solution or anything for my problem. The only solution there seems to be is closing the sockets after usage. But this i already do.

	/*
	 * Protocol: first int: Amount of data is going to be send second int: type
	 * of data third variable: data
	 */
	public void read(DataInputStream dis) throws IOException {
		int dataAmount = 0;
		dataAmount = dis.readInt();
		for (int i = 0; i < dataAmount; i++) {
			int choice = 0;
			choice = dis.readInt();
			switch (choice) {
			case 0:
				// do nothing
				break;
			case 1:
				name = readString(dis);
				break;
			case 2:
				dir = readString(dis);
				break;
			case 3:
				size = dis.readLong();
				break;
			}
		}
	}

	/*
	 * test
	 * another test
	 */
	public void write(DataOutputStream dos) throws IOException {
		int dataAmount = 3;
		if (checkSum != null)
			dataAmount++;
		dos.writeInt(dataAmount);
		dos.writeInt(1);
		writeString(dos, name);
		dos.writeInt(2);
		writeString(dos, dir);
		dos.writeInt(3);
		dos.writeLong(size);
		dos.flush();
	}

My write and read functions
read and writestring function:

	/**
	 * Read string.
	 * 
	 * @param dis
	 *            the dis
	 * @return the string
	 * @throws IOException
	 *             Signals that an I/O exception has occurred.
	 */
	protected String readString(DataInputStream dis) throws IOException {
		int length = dis.readInt();
		StringBuilder sb = new StringBuilder(length);

		for (int i = 0; i < length; i++) {
			sb.append(dis.readChar());
		}
		return sb.toString();
	}

	/**
	 * Write string.
	 * 
	 * @param dos
	 *            the dos
	 * @param string
	 *            the string
	 * @throws IOException
	 *             Signals that an I/O exception has occurred.
	 */
	protected void writeString(DataOutputStream dos, String string)
			throws IOException {
		int length = string.length();
		char[] data = string.toCharArray();

		dos.writeInt(length);
		for (int i = 0; i < length; i++) {
			dos.writeChar(data[i]);
		}
	}

A commonly class to send and recieve file info:

public class FileSendRecieve {
	Socket socket;
	OutputStream socketOut;
	InputStream socketIn;

	public FileSendRecieve(Socket socket) {
		try {
			socketOut = socket.getOutputStream();
			socketIn = socket.getInputStream();
		} catch (IOException e) {
			e.printStackTrace();
		}
		this.socket = socket;
	}

	public void sendFile(String name, String directory) throws IOException {
		File file = new File(name);
		FileInfo fileinf = new FileInfo(file);
		fileinf.write(SocketUtil.wrapOutputStream(socket));
	}

	public void recieveFile() throws IOException {
		FileInfo fileinf = new FileInfo();
		fileinf.read(SocketUtil.wrapInputStream(socket));
		fileinf.print();
	}

	public void stop() {
		SocketUtil.close(socketIn);
		SocketUtil.close(socketOut);
		SocketUtil.close(socket);
	}
}

My server:

public class Server extends Thread {

	private boolean run = false;
	private float runTime;
	private ServerSocket ss = null;
	private Socket cs = null;

	public Server() {
		runTime = System.nanoTime();
		Logger.getInstance().system("Server starting up. . . ");
	}

	public void startService() {
		try {
			ss = new ServerSocket(8081);
			run = true;
		} catch (IOException e) {
			Logger.getInstance().error(e);
			Logger.getInstance()
					.error("Port already in use, or no acces to port. Program will now exit.");
			System.exit(0);
		}
		Logger.getInstance().system(
				"Server started succesfully in: "
						+ ((System.nanoTime() - runTime) / Math.pow(10, 9))
						+ " seconds.");
		this.start();
	}

	public void run() {
		Logger.getInstance().system("Server is now accepting clients. . . ");
		while (run) {
			Logger.getInstance().system("Waiting for client. . . ");
			try {
				cs = ss.accept();
				Logger.getInstance().system("Client connected " + cs);
				new Thread(new ClientHandler(cs)).start();
			} catch (Exception e) {
				Logger.getInstance().error(e);
				Logger.getInstance().error("Something went wrong while accepting client. Program will now exit");
				System.exit(1);
			}
		}
	}

	class ClientHandler implements Runnable {
		FileSendRecieve fsr;

		public ClientHandler(Socket cs) {
			fsr = new FileSendRecieve(cs);
		}

		public void run() {
			try {
				fsr.sendFile("image.png", "c:\\");
				fsr.sendFile("image2.png", "c:\\");
				fsr.stop();
				while(true);
			} catch (IOException e) {
				e.printStackTrace();
			}
		}
	}

	public static void main(String args[]) {
		Server server = new Server();
		server.startService();
	}
}

and my client

public class Client implements Runnable {
	FileSendRecieve fsr;
	public Client(Socket socket) {
		fsr = new FileSendRecieve(socket);
	}

	public static void main(String args[]) {
		Socket s = null;
		try {
			s = new Socket("127.0.0.1", 8081);
		} catch (Exception e) {
			System.exit(0);
		}
		new Thread(new Client(s)).start();
	}

	@Override
	public void run() {
		try {
			fsr.recieveFile();
			fsr.recieveFile();
			fsr.stop();
		} catch (IOException e) {
			e.printStackTrace();
		}
	}
}
