What is Jini? What is it's place(if any) in the J2EE architecture?

Jini is an alternative distributed computing system based on RMI, serialization and the concept of "leasing". In some ways it can be viewed as a competitor for J2EE components such as CORBA, but it is really aimed at a different market.

See the comments in other threads about the interaction between Jini and EJBs/J2EE...this is definitely the most common question so far!
I did want to answer this one though:

Sun has promoted Jini as a way for small hardware gizmos to interconnect with each other. While this is certainly one possible application of the technology, I think Sun has sold Jini a bit short by focusing so much on small devices... with the result that most people think that Jini is *only* for hooking up gizmos.
Jini will find its first home in software services. It'll be used for building reliable EJB-based systems, and other, non-EJB-based backend services. It'll also be used as a way of interconnecting clients to services. It's complimentary to the J2EE model of computing; not an alternative.
I know of quite a few companies that use Jini internally as a way to architect their in-house software systems for reliability and administration-free interconnectivity.
Cheers,
