If you are writing a server application and want to use a single
IoHandler implementation with different protocols you could give
different IoServiceConfig objects for each call to IoAcceptor.bind().
Before you call bind() you configure the filter chain of each
IoServiceConfig with an appropriate ProtocolCodecFilter.
Pseudo code for chat server supporting MSN and AIM protocols:
ProtocolCodecFilter aimCodecFilter = ...;
ProtocolCodecFilter msnCodecFilter = ...;
SocketAcceptorConfig aimConfig = new SocketAcceptorConfig();
aimConfig.getFilterChain().addFirst("aimCodec", aimCodecFilter);
SocketAcceptorConfig msnConfig = new SocketAcceptorConfig();
msnConfig.getFilterChain().addFirst("msnCodec", msnCodecFilter);
SocketAcceptor acceptor = ...;
acceptor.bind(new InetSocketAddress(...), myChatHandler, aimCodecFilter);
acceptor.bind(new InetSocketAddress(...), myChatHandler, msnCodecFilter);
Please note that I have no idea how the MSN and AIM protocols actually
work. The above is only to illustrate. :-)
In SpamDrain we use the same IoHandler to service both SSL encrypted and
non SSL POP3 and IMAP connections. It works similarly to the above.
BTW, IIRC you only need MINA 2.0 if you want to have several
ProtocolCodecFilters in the same filter chain.
