Power.java
Author: Martin Olsson, molsson@csee.usf.edu
and Jakob Klamra jklamra@csee.usf.edu

This file is part of the power management service. This is a UPnP
service that will allow a device to enter power sleep mode by 
communicating with a proxy. The service has two modes: POWER and SLEEP.
The service and proxy communicates by using GENA events.

To run the program use:
java -classpath [path to Atinav library] Power
To power up the device type on, to power down type off, to exit the
program type exit.

This file contains the main function for the program. It will build
the service by providing all strings and names needed for the XML scheme.
The it registers the service and lets the Atinav SDK send events, notifications
answer discoveries and handle all other UPnP communication.

A known bug in the program is that several exceptions is received when the device
that runs the program enters power sleep mode. These exceptions are due to the fact that
notifications cannot be sent. The program is unable to recover from this error state
and must be restarted to be able to send notifications again.

The program was developed using the Atinav Java SDK for UPnP Devices.
A free trial of the SDK can be downloaded from:
http://www.avelink.com/upnp/index.htm
You need to install the SDK to be able to run the program.

This program was downloaded from http://www.csee.usf.edu/~jklamra/upnp/
and is part of a master thesis about power management in Universal Plug and Play.
Please refer to the homepage for known bugs and comments.

We do not guarantee the functionality of this program.
Use this program at your own risk.
