I have a simple question for which there is probably a simple answer
that I just haven't stumbled upon in the documentation. If I am
running a server with say 1,000 clients, and I want to push a message
to one of the clients, say client#68, how would I go about doing this
using the MINA framework? For instance, if my server is the famous
chat server example, and I wish to send a private message to
client#68, based on an asyncronous request that is triggered by an
outside process (not having every client poll for PMs).
You are going to want to maintain your own mapping of client identity
-> IoSession's, then its just a matter of getting the IoSession for
that client, and calling IoSession.write()
... alternately, you can leverage MINA's mapping that it keeps, using
IoAcceptor.getManagedSession(), but you'll need the client's
SocketAddress then to do the lookup.
I'd implement it like this:
* in your IoHandler register the client's IoSession once you have
established the client's identity with your own registry
* have a thread/task that monitor's a Queue for things-to-send-to-
clients
* the above will read off the thing to send, look up the client's
IoSession based up on the identity that the message contains
* IoSession.write() out the message to the client
