Getting a time out error

[Jere Johnson]

Hello,

I am trying to create some code that will echo a message back from the
server. But I am getting a time out error. I need some help
in figuring out what to do. thanks.

import java.net.*; // for Socket
import java.io.*; // for IOException
 
public class TCPEchoClient {
 
public static void main (String[] args) throws IOException {
 
//create input stream
InputStreamReader istream = new InputStreamReader(System.in);
//create input stream buffer reader
BufferedReader bufRead = new BufferedReader(istream);
 

//if ((args.length < 2) || (args.length > 4)) //test for correct # of arguments
//throw new IllegalArgumentException("Parameter(s): <Server> <Word> [<Port>]");
 

//ask user to enter IP address or name, port number and message to be sent
System.out.println("Enter the name or IP address of the server: ");
String server = bufRead.readLine();

System.out.println("Enter Port number: ");
String port = bufRead.readLine();
int servPort = Integer.parseInt (port);
 
System.out.println("Enter the message to be sent: ");
String message = bufRead.readLine(); // Message to be sent
 
//convert input String to bytes using the default character encoding
byte[] byteBuffer = message.getBytes();

 
//Create socket that is connected to server on specified port
Socket socket = new Socket (server, servPort);
System.out.println ("Connected to server.......sending echo string");
 
InputStream in = socket.getInputStream();
OutputStream out = socket.getOutputStream();
 
out.write(byteBuffer); //Send the encoded string to the server
 
//Receive the same string back from the server
int totalBytesRcvd = 0;
int bytesRcvd;
while (totalBytesRcvd < byteBuffer.length) {
if ((bytesRcvd = in.read(byteBuffer, totalBytesRcvd,
byteBuffer.length - totalBytesRcvd)) == -1)
 throw new SocketException("Connection closed prematurely");
 
 totalBytesRcvd += bytesRcvd;
 }
 
 System.out.println ("Received: " + new String(byteBuffer));
 
 socket.close(); //close the socket and its streams
 }
}

How well do you know the server?

Do you know that it is sending the data that you are expecting?

Did you write it? If so, make sure it is issuing a flush() call after the write. (same goes for you client).
