Jini: functional overview
> Think about how we use Yellow Pages:
– A traveler arrives in a city. (he's our client)
– He's looking for a doctor (i.e. someone who provides medical services)
– Using a Yellow Pages (i.e. a directory), he can find references to the doctors
in the city (i.e. to the service providers).
> Jini enables this kind of interaction for network services:
– The user arrives at some place with a laptop and connects it to the network.
– Wishing to print a document, he first looks for a service directory.
– He then searches for a "print" service in the directory.
– If at least one printer has previously registered its capacity to offer the
"print" service, the user will get a reference to the service.
– Finally, the print service can be invoked.
