Hi, I am a long time Java user, so I think in Java a little bit. I need
to create a TCP server and I would like to know if using the
TIdTCPServer will be good for me or if I should implement a server that
looks like this (at the bottom of the email):

my question is, : I need to know where to put all my processing of the
connection.. other than in the TCPServerExecute() method of the
IndyServer. Should I re-write my own server..can I change the way the
threads are started?

my application will be a server that accepts connection to register and
activate a software online.. with a little bit of UI.

thank you

Simon

java server->
the server:
public class KKMultiServer {
public static void main(String[] args) throws IOException {
ServerSocket serverSocket = null;
boolean listening = true;
try {
serverSocket = new ServerSocket(4444);
} catch (IOException e) {
System.err.println("Could not listen on port: 4444.");
System.exit(-1);
}
while (listening)
new KKMultiServerThread(serverSocket.accept()).start();
serverSocket.close();
}
}

thread that process the connection:
public class KKMultiServerThread extends Thread {
private Socket socket = null;

public KKMultiServerThread(Socket socket) {
super("KKMultiServerThread");
this.socket = socket;
}

public void run() {
try {
PrintWriter out = new PrintWriter(socket.getOutputStream(), true);
BufferedReader in = new BufferedReader(new InputStreamReader(socket
.getInputStream()));
String inputLine, outputLine;
KnockKnockProtocol kkp = new KnockKnockProtocol();
outputLine = kkp.processInput(null);
out.println(outputLine);
while ((inputLine = in.readLine()) != null) {
outputLine = kkp.processInput(inputLine);
out.println(outputLine);
if (outputLine.equals("Bye"))
break;
}
out.close();
in.close();
socket.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}

I would have like to have all my processing code in another class. This
class will takeover the client communication since it is not really the
best place to take care of that in the event of TIdTCPServer OnExecute
Event. By processing everything in the OnExecute Method, it will not be
good programming practice I beleive. I think the way the Java class
handles the client connexion is a good way of OO programming.

thanks for the answer

Thank you for the explanation, I have one more question..
let's say that in this case, 5 clients connect at the same time.. I
greet them in the OnConnect method..then in the execute.. I need to know
who is the client..so I write on the socket a command and then I wait
for the answer.. but is'nt the method iDTCPServerExecute will be called
by many objects at the same time and change my local variables?
I need the store the client's retreived info in the Thread's Data object?

let's say I ask for a client name, then I return to him a private key..
and I then wait for a command from the client.. If this is not done from
within the peerthread..how can I do that?

thanks

Simon
