is message sent to client

[Zlatko Josic]

Hi,

how find out is message sent to client. Server has to know is message
delivered to client.
I try something like this but it does'nt work :

IoSession session = (IoSession)context.getParameter("ioSession");
        //pisanje podatka u sesiju.
         WriteFuture future =
session.write(transformator.transform(context.getResponse().getParameters()));

    future.addListener(new IoFutureListener<IoFuture>(){

            @Override
            public void operationComplete(IoFuture ioFuture) {
                try{
                    WriteFuture newFuture = (WriteFuture)ioFuture.await();

                    if (newFuture.isWritten()){
                        //podatak je poslat terminalu.
                        log.info("podaci su poslati terminalu
"+terminal.getId());
                    }else{
                        log.info("podaci nisu poslati terminalu
"+terminal.getId());
                        //provera da li je doslo do greske pri slanju
odgovora.
                        Throwable t = newFuture.getException();
                        if (t != null){
                            log.error("Greska u slanju odgovora
terminalu",t);
                        }
                    }
                }catch(Throwable t){
                    log.error("Greska ", t);
                }

            }});
