Jini is a collection of services (hardware, software, or both)
|
|
When "a Service" connects to the network, it sends a small "hello" packets (512 bytes) to announce its existence
|
|
Jini "Lookup Service" notices this packet and query the service to discover it capabilities, and makes this info available for other devices on the network
|
|
Then the Service registers with the Lookup Service, it provides a proxy object
|
|
When a client wants to use a service (for example scanner) it asks the Lookup Service to provide info about available services (the Lookup service provides a copy of the proxy object. The client makes calls to the proxy object that arranges to do the work)
