Take a look at the online documentation, specifically
http://mina.apache.org/iofilter.html
If you've got any questions after that, ask 'em here!

Thanks Maarten.
I didn't fully understood? Sorry, I'm a newbie.
Inside my server coding, I have this line of code:
acceptor.bind( new InetSocketAddress(PORT), new ServerSessionHandler(),
cfg);
Where ServerSessionHandler handle the server and client input output.
Where should I insert your sample coding?

Hello,
I think an authentication filter will always be tightly coupled with the
protocol: the filter needs to know whether
the user is already authenticated and what the authentication command is.
Here is an example :
public class AuthenticationFilter extends IoFilterAdapter {
protected Logger logger = LoggerFactory.getLogger(
AuthenticationFilter.class);
private NotAuthenticated notAuthenticated = new NotAuthenticated();
public void messageReceived(NextFilter nextFilter, IoSession session,
Object message) throws Exception {
User user = (User) session.getAttribute("USER");
if (user != null || message instanceof LoginCommand) {
nextFilter.messageReceived(session, message);
} else {
logger.warn("not authenticated => reply with error
message");
session.write(notAuthenticated);
}
}
}
Add the filter to the chain AFTER the ProtocolCodecFilter.
Let us know if you have any better ideas.

Thank you!
