Service Portal for Jini Federations

Today, there are two different ways to use computer. The first one is using standalone applications and another is using network services. Because user must install all program files into personal computer for standalone application, the cost of installing and updating application is very expensive. Online service is always constructed by using the model of a mainframe, so information is still administered in the centralized database and every user's operations must be processed in the web server.
Because of the mature network infrastructure, people can use different ways to connect to Internet. More and more applications are changed to online services. That is also the ideal of Sun, "The Network is The Computer", and Sun announces Jini technology for the ideal. By using Jini technology, service providers can construct and deploy their services easily and users can find these services easily. Jini technology is based on Java, so Jini has many advantages of Java. Besides, there is a concept of federation in Jini technology. People can share resources in the same federation easily, but can not access resources in the other federation. In the other words, federations can not communicate with each other.
In order to solve this problem, we design Service Portal for Jini federations, that let Jini federations can share their resources with others. In the Service Portal for Jini federations, we use "Service Proxy Forwarding" mechanism to forward service proxy objects inside Jini federations and use "Scalable Service Portal" mechanism to gather service proxy objects from different Jini federations.
In our service portal system, we implement two application services to determine the reliability of the system. They are Stock Market System and Motor vehicles Presentation System.
