I m trying to write a two-user tic tac toe using JSF technology. From the books and tutorials I ve read I understand how JSF s work and how to write a web-app for one user to use, say a Celsius to Fahrenheit converter or something like that.
我在任何地方都找不到的是如何以两个用户（在不同的计算机上）实际上可以相互连接并相互玩井字游戏的方式实现该应用程序。所以我想我必须以某种方式为这两个用户授予特定Bean的访问权限，通过登录进行身份验证，但是，Bean本身必须知道哪个用户正在采取行动，这样游戏才能轮流进行。
有任何已知的方法来实现这样的东西吗？有人能给我一个关于这个话题的教程或其他东西吗？

截至目前，除其他外，PrimeFacesJSF组件库有a<；p:push>；组件（单击链接查看实时示例），它使用
只需尝试PrimeFaces网站上提供的示例，您就会了解如何实现您的井字游戏想法。
