As we enter the 21st century, our dependency on the Internet is going to increase each day. This observation has inspired many researchers to invest their efforts into the development of efficient Web-based computing paradigms. Java-RMI is one alternative offered by Sun Microsystems. Using Java-RMI, a software developer can easily design and develop collaborative systems. In this article, we describe the use of Java-RMI in designing a collaborative information classifier, called D-SIFTER. We also present the principles of RMI, the details of our prototype, and some of the results from the preliminary experiments with it.
