I need to write a server for a game, which is closer to action type game, so needs fast communication. There must be only one server, I'll just split the world in zones, but this is not the question.
Client will be written in java using jMonkeyEngine. In my opinion I should write the server in java. I don't want to implement any low level features such as communication, reliable udp, etc. Can you suggest any java libraries that already implement this? Or maybe there is more suitable languages to implement this project (must run on linux)?
