Abstract The principle and characteristic of Jini are introduced in this paper. Aiming at a chemical virtual experiment system, a network service-oriented virtual experiment platform based on Jini techniques is designed. The platform is constructed by introducing the mechanism of collaborative service. Its function and architecture are described in details. Some operating rules of the platform are declared based of Java interface techniques, and a series of service-oriented interfaces of the system are defined. The running principle and flow of the platform are illustrated by the example of Fe and sulfuric acid chemistry action. The system can animatedly displays chemical experiment process with expansibility, reliability characteristics.
