I am trying to write a simple client/server Echo application, my client seems to be sending the input, but the server doesn't seem to pick it up and send it back.
Here's the server:
import java.io.*; import java.net.*; public class Server { public static void main(String args[]) throws Exception { int port = 2000; ServerSocket serverSocket; Socket client; BufferedReader is = null; BufferedWriter os = null; serverSocket = new ServerSocket(port); System.err.println("Server established on port " + port); client = serverSocket.accept(); System.err.println("Client connected"); is = new BufferedReader( new InputStreamReader(client.getInputStream())); os = new BufferedWriter( new OutputStreamWriter(client.getOutputStream())); System.err.println("Server established on port " + port); String message = ""; while((message = is.readLine()) != null) { System.err.println("Messaged received " + message); os.write(message); } is.close(); os.close(); serverSocket.close(); } } Then, the client looks like this:
import java.io.*; import java.net.Socket; public class Client { public static void main(String args[]) throws Exception { String host = "localhost"; int port = 2000; Socket socket; socket = new Socket(host, port); BufferedReader is = new BufferedReader( new InputStreamReader(socket.getInputStream())); BufferedWriter os = new BufferedWriter( new OutputStreamWriter(socket.getOutputStream())); System.err.println("Connected to " + host + " on port " + port); BufferedReader br = new BufferedReader(new InputStreamReader(System.in)); String input = ""; while((input = br.readLine()) != null) { System.out.println("Sending " + input); os.write(input); System.out.println("Receiving " + is.read()); } is.close(); os.close(); socket.close(); } } What am I missing, I am sure I overlooking something simple.
