Yes. Like when you're using Java applet. Your game will be wrapped in a .jar file and deployed to the Web server. Users come and click the Web page, the game just runs. That's all.

But If there is no Java plugin on their machines, they will be pointed to where they can download it. After installing plugin, the game runs.
