Spring also provides support to expose POJO's over RMI. I don't think you can find anything that supports simple TCP/IP sockets (using NIO or blocking IO) as the protocol itself will be tightly coupled with the objects you pass in between and the order they are passed in (e.g. A function with 1 parameter will only need a serialized object passed through whereas a function with 2 parameters will need 2 objects, and the order will be important etc).
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
