Abstract: Nowadays JavaScript is re－valued, and its running environment is shifting gradually from traditional web client－side to server－side. As a typical representative of server－side JavaScript engine, Rhino has a broad platform support and appling foundation. By placing Rhino engine into a standard Java servlet, a server－side JavaScript container can be constructed. With the help of Rhino engine, developers can not only access Java objects inside JavaScript container, but also gain full support of Java platform. Meanwhile, server－side JavaScript also unified development language used in both front and back end. Thus, it reduces the difficulty of web development and improves efficiency.

Key words: JavaScript engine, server page, Java servlet
