GetPowerStatus.java

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 action that can be invoked on the service. The action
allows a control point to get the status of the power management. The
action will return true if the device is powered up or false if the device
is powered down.

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.
