Where to Start?
Rio is distributed under the Apache License, version 2.0.
Rio requires JDK 1.7.x or greater.
Rio is distributed with dependencies. Dependencies are additional software required for running Rio. Note that each of these libraries is subject to the respective license; check the respective project distribution/website before using any of them in your own environment.
The distribution includes the following third party technology: Apache River 2.2.2 (Jini), Hyperic SIGAR, Commons Compress 1.0, Groovy, SLF4J, Logback and the Prefuse Visualization Toolkit.
To install Rio on Linux or OS/X, unzip the distribution package to the desired installation directory. For example, to install into /opt:
unzip rio-5.6.zip -d /opt
This creates a directory called rio-5.6 under /opt
To install Rio on Windows, unzip the distribution package to the desired installation directory. You should use a zip application such as 7zip, not the built-in folder decompression. Note that both Windows and Java 5 have some issues with long file names and file paths, as well as with spaces in directory names. We recommend installing into a directory of your chosen drive, and ensuring that directory names do not have spaces (like C:\Program Files).

Once you have unzipped the distribution, you will have a rio-5.6 directory containing the following items:
- bin - The directory that contains command to start Rio services
- config - Directory that contains configuration for Rio services and platform
- deploy - The default deploy directory used to serve deployed application resources.
- docs - The directory that contains API documentation, and other documentation

You can create a Rio project in seconds using the Rio Archetype. Simply run:
You will be prompted to enter the artifactId, service to create (this will be the classname of the service interface), the groupId, version and package name.
The RIO_HOME/bin directory contains starter script (and .cmd) files to start Services and Utilities provided by Rio.
The rio script is the the command and control utility for starting Rio services and the Rio command line interface. All of the other scripts are wrappers around the rio script. The convention for starting services using the rio scripts is as follows:
- rio start service-starter
- rio start cybernode
Will use the config/start-cybernode.groovy file
- rio start all
Will use the config/start-all.groovy file
The following scripts are shortcuts for starting the basic services in Rio:
- cybernode - Starts a Cybernode and a Webster on an anonymous port
- monitor - Starts a Provision Monitor, a transient Jini Lookup service and a Webster on port 9010
- webster - Starts a Webster on port 9010
- startall - Starts a Webster on port 9010, a Cybernode, Provision Monitor and a transient Jini Lookup Service
By just running rio, you will be put into the interactive command line shell:
Welcome to the Rio Interactive Shell Program. You can interact with the Rio using the following commands : list http deploy destroy dir help pwd jconsole redeploy set undeploy cd ls stats For help on any of these commands type help [command]. To leave this program type quit rio> _
