JINI is a new technology implemented in pure Java ontop of the JDK 1.2. It defines a framework for the interaction of services and service-consumers. Design goals were simplicity, reliability and scalability by low to none administration overhead (e.g. no drivers to install). You can find information about JINI at various places like http://developer.java.sun.com/developer/products/jini or http://www.jini.org.
This page is no introduction to JINI. It just wants to give some hints for using JINI together with Linux and provides some sample code. It wont be of any help if you don't have an understanding what JINI is about and how it works.
Since JDK 1.2 is available for Linux, there is no problem running JINI on the Linux operating system. There is one thing to watch out for: a core feature of JINI uses IP-multicasting. If you don't know what this is, check out the appropriate HOWTO. Make sure that the kernel you are using is multicasting enabled. You also have to put the interface in multicasting mode and set a correct route:
# ifconfig lo multicast # route add -net 22.214.171.124 netmask 240.0.0.0 dev lo
You can download two tarballs. One with scripts useful in
setting up the JINI environment (e.g. a script starting the
lookup service, a webserver and the RMI activation deaemon) and
one with a sample application. This
application is a service
making all entries in the local
available for clients in the JINI-community. A simple client is
also supplied for testing purposes.
