    <p>I have a simple server-client program that takes info from the client and passes it to the server. The messages are passed through a DatagramSocket. The server then takes the message and writes it to a text file.</p> <p>My initial message works fine(gets printed to the file). However, if I run the client again then the new message does not get written to the file. I have to RESTART the server for the message to be printed again.</p> <p>I have an arrayCopy method that copies two arrays and puts it into a larger array.</p> <p>CLIENT</p> <pre><code>public static void main(String[] args) throws IOException { System.out.println("Enter Username"); BufferedReader usernameInput = new BufferedReader(new InputStreamReader(System.in)); // Get the Username String username = directoryInput.readLine(); byte[] usrname = username.getBytes(); //Copy Username to Array byte[] tempArray = copyarray(packetheader, usrname); buffer = tempArray; mypacket = new DatagramPacket(buffer, buffer.length, IPaddr, 40000); clientSocket = new DatagramSocket(); clientSocket.send(mypacket); </code></pre> <p>Server</p> <pre><code>public static void main(String args[]) throws Exception { String Database; textfile = "C:\\textfile.txt"; DatagramSocket serverSock = new DatagramSocket(40000); byte[] rbuf = new byte[97]; DatagramPacket recievedPacket = new DatagramPacket(rbuf, rbuf.length); serverSock.receive(recievedPacket); String byteToString = new String(recievedPacket.getData(), 0, recievedPacket.getLength(), "US- ASCII"); FileWriter fstream = new FileWriter(textfile); BufferedWriter out = new BufferedWriter(fstream); out.write(byteToString); out.close } </code></pre>
