You answered that question for me - thank you for that. I was hoping that I wouldn't need to deal with the sessions, but it's easy enough to deal with. I think what you just basically described is in the chat example that comes with MINA.
I can add a method to look up the session as described and write the data to it. The other question that I have, is where should the method be called from? For example, if I have a JMS consumer that consumes a message with instructions to deliver a packet to a certain IP address, should that method access the IoHandler through the class that created the acceptor? (acceptor.getHandler().insertMySendMethodHere()?) Thanks again, Jeremy > OK I think I see now. Even though UDP is stateless, MINA still associates > a > IoSession with clients.
