JINI is a Java based networking architecture that is designed for distributed computing and is based on Service Oriented Architecture. It is an open source software architecture that can be used to design and implement adaptive, scalable distributed systems. Jini technology includes JavaSpaces Technology and Jini Extensible Remote Invocation (Jini ERI).  Jini is "highly flexible" and "adaptive to change" irrespective of its implementation in hardware or software. Jini network technology suffices to the requirements of any dynamic computing environment for building adaptive networks that are highly flexible, scalable and evolvable. You can consume a JINI enabled service from a service consumer or a program once it announces itself, i.e., makes its presence felt in the network. JERI is Jini Extensible Remote Invocation and may be defined as a new implementation of the Java RMI programming model.
