Hello Daniweb. I'm new to Java, and I love learning it and want to continue learning it. I was curious about how a Java chat server could be made so I found an open source very basic one online. But the problem is when I run the server it gives me a default ip of 0.0.0.0 I want to be able to specify my own ip in the source. Any help would be greatly appreciated!
import java.net.*;
import java.io.*;
public class ChatServer implements Runnable
{ private Socket socket = null;
private ServerSocket server = null;
private Thread thread = null;
private DataInputStream streamIn = null;
public ChatServer(int port)
{ try
{ System.out.println("Binding to port " + port + ", please wait ...");
server = new ServerSocket(port);
System.out.println("Server started: " + server);
start();
}
catch(IOException ioe)
{ System.out.println(ioe);
}
}
public void run()
{ while (thread != null)
{ try
{ System.out.println("Waiting for a client ...");
socket = server.accept();
System.out.println("Client accepted: " + socket);
open();
boolean done = false;
while (!done)
{ try
{ String line = streamIn.readUTF();
System.out.println(line);
done = line.equals(".bye");
}
catch(IOException ioe)
{ done = true; }
}
close();
}
catch(IOException ie)
{ System.out.println("Acceptance Error: " + ie); }
}
}
public void start()
{ if (thread == null)
{ thread = new Thread(this);
thread.start();
}
}
public void stop()
{ if (thread != null)
{ thread.stop();
thread = null;
}
}
public void open() throws IOException
{ streamIn = new DataInputStream(new
BufferedInputStream(socket.getInputStream()));
}
public void close() throws IOException
{ if (socket != null) socket.close();
if (streamIn != null) streamIn.close();
}
public static void main(String args[])
{ ChatServer server = null;
if (args.length != 1)
System.out.println("Usage: java ChatServer port");
else
server = new ChatServer(Integer.parseInt(args[0]));
}
