1. JINI Goals

• Federating groups of devices and software
  components into a single, dynamic distributed
  system
• 1. Enabling users to share services and resources
  over a network
• 2. Providing users easy access to resources
  anywhere on the network
• 3. Simplifying the task of building, maintaining,
  and altering a network of devices, software

3

• The Jini system extends the Java application
  environment from a single virtual machine to a
  network of machines
• Targeted to the workgroup, possible extend to
  large organization

3.1 Services

• Services in a Jini system communicate with each
  other by using a service protocol---a set of
  interfaces written in the Java programming
  language.
• Communication is done by RMI
• RMI allows not only data to be passed from object
  to object around the network but full objects,
  including code
