what I need is acceptor needs to take 'n' requests simultaneoulsy.
Ok, so when you define your acceptor, you can provide a number of
IoProcessor to use, depending on the number of processor you have. The
Executor is a bit different beast : it's used if you have a long
processing part somewhere in your chain, and want to decople this part
from the processing of faster request. Not sure that you need it, it all
depends on your application.
Basically, the number of IoProcessor defaults to Nb CPU * 2 + 1. You can
change that by using the NioSocketAcceptor( int nbProcessor ) if you
want to have more processor in the pool.
You have to know that a processor is associated with a Selector, so once
a session has been registred within a IoProcessor, eveery message
received or sent on this session will be processed by this IoProcessor.
If you have some lengthly operation affecting one special message, then
this IoProcessor will wait until this processing is done before
processing the next incoming or outgoing event. However, all the other
sessions associated with another IoProcessor will be processed in parallel.
Last, not least, if you want an IoProcessor not to be stuck while
processing a request, just add an executor in the chain, so a pool of
thread will be used to process the messages, instead of the IoProcessor
thread.
In any case, before using an Executor, I would engage you to make your
server working with the default configuration, because it's most likely
be enough for your need. Once you have reach a point where your needs
aren't met with the default config, then either increase the number of
IoProcessor, or add an executor to the chain :
filterChainBuilder.addLast("threadPool", *new* ExecutorFilter
<http://mina.apache.org/report/trunk/xref/org/apache/mina/filter/executor/ExecutorFilter.html>(Executors.newCachedThreadPool()));
// Here, we use an ubound thread pool.
Hope it helps.

Hey, you can post as many time as you want, but you won't get any help with
such a vague question...
