I am currently developing an online game where two players can play against each other (something like Who Wants to Be a Millionaire?). And I would like to implement an asynchronous service so those two players can send asnwers to each other (and I don't want them to wait) but I don't know where to start, what is the best solution for such a problem?
I am using Spring as a backend and pure JSPs and jQuery on frontend. So after little research I came to Atmosphere framework, is this what I want?Or maybe some JS based solution like Socket.IO would work too?
