[B]Simple Client connected to server but not exchanging messages[/B]

[JavaEmpires]

Hello all,
I m new to Networking.
I m trying to write a simple client-server program wherein server greets client when connected and vice versa.

Here's is a complete Client and Server program.

/*Server.java*/

public class Server extends Thread {
public static final int V_PORT = 2013;
protected ServerSocket server_socket;

public Server()
{
try{
InetAddress iaddr = InetAddress.getLocalHost();
server_socket = new ServerSocket(V_PORT, 5, iaddr);
System.out.println("\nConnected to InetAddress " + server_socket.getInetAddress().toString());

System.out.println("\nPort " + V_PORT+" is up and running");

}


catch(Exception e){
System.out.println("\nError : Port " + V_PORT+" is already used by another process");
}
}



public void run(){
InputStream receive;
OutputStream send;
String msg = "Hello Client WelCome!";
String output="";
byte b[] = new byte[100];
while(true){
try{
Socket client = server_socket.accept();
send = client.getOutputStream();
send.write(msg.getBytes());
receive = client.getInputStream();
receive.read(b);
System.out.println("\nClient Said : "+ b.toString());



}
catch(Exception e){
System.out.println("\nCould not connect to client" + e.toString());
e.printStackTrace();

}
}

}

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

/*Client.java*/

public class Client {

public static final int V_PORT = 2013;
public Socket client_socket = null;
InputStream receive = null;
OutputStream send = null;
String msg="Hello Server";

public Client(){
byte b[] = new byte[100];
try{
InetAddress addr = InetAddress.getLocalHost();
client_socket = new Socket(addr, V_PORT);
System.out.println("\nConnected to port " + V_PORT);
System.out.println("\nConnected to InetAddress " + client_socket.getInetAddress().toString());
receive = client_socket.getInputStream();
receive.read(b);
System.out.println("\nString read from Server = "+b.toString());

send = client_socket.getOutputStream();
send.write(msg.getBytes());
System.out.println("\nMessage Written to the server");


}


catch(Exception e){
System.out.println("\nClient Error : "+e.toString());
}
}


public static void main(String args[]){
new Client();
}
}

Please help me to resolve this problem.

Thanx in advance.

I'm not sure I see your problem. See my screenshot to see that I was able to send a message to the server from the client, also upon connect a message was sent from the server.



Appears to work.. no? just not sure what it is you're requiring it to do exactly.

The problem you are seeing comes from the line:

System.out.println("\nString read from Server = "+b.toString());

This line is calling toString() on the byte array - which by default is simply printing the memory address. I suspect what you are trying to do is print the contents of the byte array, you need to create a string from the bytes:

System.out.println("\nString read from Server = "+ new String(b));

Hope that helps

Thank you all.
That solved my problem.
Thank you very much
