Hi James,
That's an interesting statement that using an open source project gives
you less control and more cost than home-grown project, althought it might
depend on the responsiveness and openness of the project community. If
you are interested in XMPP, I'd recommend the following XMPP servers,
which are both based on MINA:
* OpenFire
* Apache Labs Vysper
Vysper might be more interesting to you in terms of licensing.
If not interested in XMPP... then here's my idea about your question:
If your business logic can be executed simultaneously, choose the first
approach. If the business logic should be executed one by one per
connection, then choose the second approach.

Hi Gato,
Thank you very much for your kindly reply.I cannot use Open Fire for
some reason,for which it doesn't meet our business logic very exactly
and we need a server that was fully controlled by ourselves,basing on
Open Fire which will raise our development and maintainence costs too.So
I still need to know the answers to the question I mentioned in my
original mail.
BTW I cannot understand what you said 'By no means I'm trying to "steal"
you from MINA ' very well :(.
Best Wishes

Hey James,
By no means I'm trying to "steal" you from MINA :) but have you checked
Openfire ( http://www.igniterealtime.org/projects/openfire/index.jsp ).
Openfire is an XMPP (aka Jabber) server built on top of MINA. XMPP is
the open standard for IM.

Hi folks,We have built our IM server based on MINA.It's excellent!Thanks
for you guys' hard work!I have a question to ask,thanks in advance!
snippet codes as followed:
public class TcpHandler extends IoHandlerAdapter
{
private static final Logger logger =
LoggerFactory.getLogger(TcpHandler.class);
@Inject
private ITaskProcessor taskProcessor;
@Inject
private ISessionManager sessionManager;
@Inject
IHarvestServerContext context;
public void sessionCreated(IoSession session)
{}
public void sessionClosed(IoSession session)
{}
public void sessionIdle(IoSession session, IdleStatus status)
{}
public void exceptionCaught(IoSession session, Throwable cause)
{
session.close();
}
/*
* receive any incoming complete packets
*
* @see
org.apache.mina.common.IoHandler#messageReceived(org.apache.mina.common.IoSession,
* java.lang.Object)
*/
public void messageReceived(IoSession session, Object message)
{
/*question is here,when messages have been received,I want to do our
business logic in two different ways,but I dunno how to profile them to
see which one's performance is better.*/
1 put message into a array,then a multithread business logic
processor keeping getting one from the array to do business logic.Then
after the processing,if there are messages that need to be sent-back or
broadcasted to clients ,add them into another array then still a
multithread messages sender keeping getting one from the array to send
it to client.
2 just do business here.Then after the processing,if there
are messages that need to be sent-back or broadcasted to clients ,just
send them
}
}
TKS a lot!
