Alive and well: Jini technology today

The Jini community is an ongoing experiment in trying to mix open source development techniques with industrial engineering development. The Jini technology is an approach to distributed systems that uses several Java properties. In particular, the Jini environment makes heavy use of Java's ability to move objects, including each object's data and code, from one Java environment to another. The Java environment, with its portable bytecodes, dynamic loading, code verification, and security allows such an approach straightforwardly. The author discusses its core services, discovery protocol, device connection and system enhancement.
