Jini Technology is
based on Java™ technology. It Enables all types of devices to simply connect
into impromptu networks, making access to and delivery of new network services
as simple as plugging in a telephone.It Enables all types of digital devices to
work together in a community put together without extensive planning,
installation, or human intervention.Each device provides services that other
devices in the community may use.
An impromptu community is another way
to describe what happens when two or more devices using Jini technology come
together to share their services. It is impromptu, because the devices do not
need any prior knowledge of each other in order to participate. Jini technology
allows devices to dynamically establish communication to share and exchange
services across a network. The impromptu community is a dynamic environment
that eliminates the need for configuring devices or installing drivers. For
example, imagine plugging a camera into a network. The camera instantly joins
the network without drivers to install, floppies or a CD-ROM to insert, or
keyboard commands to type. The camera identifies itself and offers its
services. If the camera could talk, it would be saying: "I'm a camera,
anyone need pictures?" You might have a laptop that uses Jini technology
to join this network. You could access the camera, snap a photo, route it to
your own disk drive (which also uses Jini technology to communicate with other
devices), or send it to another device for printing .
These devices provide
their own user or programmatic interfaces, which ensures reliability and
compatibility. The overall goal is to turn the network into a flexible, easily
administered tool on which resources can be found by human and computational
clients. The focus of the system is to make the network a more dynamic entity
that better reflects the dynamic nature of the workgroup by enabling the
ability to add and delete services flexibly.
History of
Jini Technology
• The idea of the Jini system sprang from
Sun cofounder Bill Joy at Sun Aspen Smallworks R&D lab in 1994.
• Under the leadership of Bill Joy and Jim
Waldo
• Ann Wollrath, the inventor and designer
for Java Remote Method Invocation (Java RMI)
• Ken Arnold, the designer of JavaSpaces™
technology.
• Bob Scheifler, a principal of the X
Consortium and designer of Lookup/Discovery.
• Based on the potential to create a
ubiquitous network by leveraging the unique distributed computing
characteristics of Java technology .
• On January 25, 1999, Jini was officially
launched and the technology is available for download.
• Sun currently has agreement with a wide
range of technology companies to develop Jini technology services, both
hardware and software . Company includes Axis, Canon, Datek, Epson, FedEx,
Mitsubishi, Norwest Mortgage, Novell, ODI, Quantum, Seagate, Toshiba, Computer
Associates, Oki, and Salomon Brothers.
• It is expected that by using Jini technology, we can enable infinitely
connected network of services into which anyone will be able to
plug-and-participate anytime, from anywhere, using the simplest possible
technology.
