Hi all,

I need your advices on design.
Problem is designing "core engine" for media player. And what type of patterns need to be used.
Core Engine's functionalities are: play, pause, stop, chapter change, title change, and so on.
When core engine receives any user operation it must decide from where to where play that movie.
In general, core engine gives playlist to presentation engine which have decoders.

Thanks a lot to Sandeep Awasthi, for understanding me serious.

good idea

Hello to all,
I have started work as a Java Developer for 1 month ago.

Please advice me,
how to become Software Architect ?

I have a threads synchronization problem but how to solve this problem i don't know.
Concrete problem is >>> server sends response before clientthread catches readObject()
and clientthread waits this response...

Please see my code:

class ClientThread extends Thread { private Client client; private Socket socket; private ObjectInputStream ois; private boolean quit = false; ... ClientThread(Client client, Socket socket) { this.client = client; this.socket = socket; } @Override public void run() { try { ois = new ObjectInputStream(socket.getInputStream()); } catch (Exception e) { } while (!quit) { try { System.out.println("CT: Reading serverThread object"); Response response = (Response) ois.readObject(); System.out.println("CT: response.Message--" + response.getMessage()); System.out.println("CT: response.Code--" + response.getCode().toString()); if (response != null) { client.readResponse(response); } else { System.out.println("Null response"); } } catch (Exception e) { System.out.println("Error: on listening server response"); quit = true; break; } } System.out.println("CT quit.."); } }

And here is my ServerThread:
class ServerThread extends Thread { private ObjectInputStream ois; private Socket socket; private boolean quit = false; private Server server; ServerThread(Server server, Socket socket) { this.server = server; this.socket = socket; } @Override public void run() { try { ois = new ObjectInputStream(socket.getInputStream()); } catch (Exception e) { System.out.println("ERROR: (ST) in socket inputStream"); } while (!quit) { try { Command command = (Command) ois.readObject(); System.out.println("ST-----readobject:" + command.toString()); Response response = command.execute(server); server.sendResponse(socket.getOutputStream(), response); } catch (Exception e) { System.out.println("ERROR: socket command reading"); break; } } System.out.println("ST: quit...."); } }

I have found IBM 's whitepaper for "how must be simple client/server chat application".
Problem is: how must be architecture of more complex chat application with PROTOCOL like:
(-r <nick> <name> <pwd> // register new user)
(-s <nick> <pwd> // signin user)
(-q //quit from chat)
and others.
For example, I have code
ChatClient - start client
ClientThread - din/dout
ChatServer - start server
ServerThread - din/dout for every chat client

Thanks a lot to Rob !!!
I have found in C/C++ _kbhit() function for this purpose and getc() also.

Dear Java professionals! advice me please

>>>problem with console chat application.

is there any way of handling user keypress in console (is user typing any message or not!!!) ?
i have tried :
BufferedReader br = new BufferedReader(
new InputStreamReader(System.in));
.....
a) int i = br.read();
............
b) if (br.ready())
............
c) DataInputStream dis = .....
if (dis.available() == 0)

this methods require of ENTER (CR) key press.
but by these methods i cannot get, Is user typing or not !
