Hi=20

I am now aware how I/O processor thread working on MINA framework. It seems
like I/O processor thread=20

in threadpool processing new connection event. But I am not sure how exactl=
y
it works. =20

Below is my Codes to start Server Process : =20

NioSocketAcceptor acceptor =3D new NioSocketAcceptor();
           =20
acceptor.getFilterChain().addLast(
     "protocolFilter",
         new ProtocolCodecFilter(
                new myCodecFactory()));
           =20
acceptor.getFilterChain().addLast("threadPool", new
ExecutorFilter(Executors.newCachedThreadPool()));
           =20
Regards,
