It presents a case for leasing functionality within evolving B2B e-markets and auctions. If you've integrated systems across a network, you know that the resiliency of the network and the ability to cope with network failures separates good applications from primitive ones. Jini assumes at its foundation that the network may be unstable. Jini introduces the idea of a lease to service management. If you are a user of a service, you never own the service, you simply lease it.
Nothing is permanent.
All resources must have some management process that periodically checks to see if everything is okay and to determine whether the resource is still required by the user. Imagine I am a service provider publishing services offered to B2B exchanges. My system crashes, or I am having system problems. There's not likely to be a consistent approach across exchanges. Leasing is an important part of Jini infrastructure robustness.
