Jini™ Specifications, The, Second Edition

DA.2. Basic Device Architecture Examples

NOW we will look at three different approaches for implementing a a Jini technology-enabled service in hardware. Each of the approaches will look the same to a client of the service. Each approach takes a different route to interacting with the Jini lookup service and in providing an interface written in the Java programming language to clients of that service. In each case, a different trade-off was made between the complexity of the device, the flexibility of the device, and the directness of the communication between the client wanting to use the service and the device that implements the service.

All but the first of the examples make use of interposition, that is, the ability of a service to add ...
