So I end up with wanting to use an IoFilter to parse the 1st layer messages, then have an IoHandler process it (optionally sending keepalive messages and do other stuff for layer1), then I want it to go to another IoFilter that parses the 2nd layer message and then finally end up in the IoHandler for the 2nd layer protocol. In a way, similar in setup if you had to implement TCP + an application protocol. How can this be done with MINA? Simply putting the 1st layer protocol handler in a filter also? That doesn't seem to be what's intented - having looked at the MINA presentation slides - but will it at least work?
I would suggest implementing each layer as an IoFilter. Just because an IoFilter receives a message, it does not mean that it must pass the message on. Thus, your layer 1 IoFilter can send our responses for keep-alive without disturbing layer 2 and beyond.
