java - How can I connect two users so they can share common object (game instance) with use of J2EE web technologies (JSP, Spring etc.)? -

I think Player 1 creates a game (for two players), the server returns the URL, player 1 This url sends the player 2 and player 2 to the URL and which adds to the game.

What is the easiest and easiest way to achieve this using JSP and related technologies?

You will need to store this information in something in the map You can pass the key around all the parameters or pathinfo in the request URL, when you encounter a request, then you check the presence of parameters or pathmarks, and then get the associated code from map Please.
