Jini technology- advanced set of network protocols Jini is a set of APIs and network protocols that can help you build and deploy distributed systems that are organized as federations of services. A service can be anything that sits on the network and is ready to perform a useful function. Hardware devices, software, communications channels -- even human users themselves -- can be services. A Jini-enabled disk drive, for example, could offer a "storage" service.

Share this item with your network: Jini pronounced DJEE-nee like the Arabic word for "magician" is a network architecture concept that Sun Microsystems calls "spontaneous networking. Each pluggable device will define itself immediately to a network device registry. When someone wants to use or access the resource, their computer will be able to download the necessary programming from it to communicate with it.
No longer will the special device support software known as a device driver need to be present in an operating system. The operating system will know about all accessible devices through the network registry.
Jini can be viewed as the next step after the Java programming language toward making a network look like one large computer. Jini promises to enable manufacturers to make devices that can attach to a network independently of an operating system like Windows Equipped with its own small, special-purpose and possibly microchip-embedded operating system, a printer could be plugged into a network and immediately shared by users at a mix of computers: Windows, Macintosh, UNIX.
Mobile devices could be transported and easily plugged into a network so that others could use the device. For many devices, the operating system can be much smaller than Windows , for example, since it is serving only the functions that device requires. When a device is plugged into the Jini network, it is immediately registered by the Directory Service layer as a member of the network. Its necessary program object s are placed in a JavaSpace layer so that other network members can discover and download them when that network member wants to use the device.
The layer supporting the boot, join, and discover protocols enables devices, users, and applications to announce and register themselves and to discover others.
Jini Network Technology
This technology provides a flexible infrastructure for delivering services in a network and for creating spontaneous interactions between clients that use these services regardless of their hardware or software implementations. Concepts introduced by this technology such as leasing discovery and the movement of objects over a network vastly simplifies interaction on a network embedding a great degree of resiliency and scalability within a distributed system. Companies are using this technology to build communities of services out of simple piece of hardware and software that have been built according to it s specification. Examples ranges from business enterprises, medical systems, financial applications, and battlefield implementations, to a Jini enabled car or a Smart House.

History Edit Sun introduced Jini in July In November , Sun announced that there were some firms supporting Jini. The Jini team at Sun Microsystems has always stated that Jini is not an acronym. Ken Arnold has joked that it means "Jini Is Not Initials", making it a recursive anti-acronym ,  but it has always been just Jini.
