Your assignment

• If temperature is above 20 degrees the DiscoBall
  should be rotating.
• When windspeed exceeds 2 the Light should flash 3
  times.
• Windspeed can be altered by turning on Fan in
  front of Windmeter.
• When leaving application Fan and DiscoBall should
  be turned off.

1. Set up the environment

• Download Axis 1.4 (http//ws.apache.org/axis/)
  and install it following the instruction provided
  in the webpage.
• We will use Eclipse as the IDE to create the
  first Hydra application in Hydra
• You can of course use any other IDE or text editor

5
2. Create a PHP project

• Create a new Java proyect and create a class for
  your application.

• Add the axis libraries to the classpath of your
  project

3. Web Service References

• You will use these endpoints to consume the
  services
• DiscoBall http//212.214.80.1618080/3/BasicSwitc
  hWS
• Fan http//212.214.80.1618080/4/BasicSwitchWS
• Light http//212.214.80.1618080/2/EnhancedSwitch
  WS
• Thermometer http//212.214.80.1618080/Thermomete
  rWS
• Windmeter http//212.214.80.1618080/WindmeterWS

4. Create the Java Client code using axis

• Open a command console and create the Java client
  code for each service, providing the path to the
  wsdl file
• java -cp AXISCLASSPATH org.apache.axis.wsdl.WSD
  L2Java -u http//212.214.80.1618080/3/BasicSwitc
  hWS?wsdl

This will generate for you the client code.
Repeat this operation and copy the code generated
to your project.

MalformedURLException, ServiceException,
NumberFormatException, RemoteException //Get
the services for each device IHydraThermometerWSSe

5 Finalise your Code
//Start coding the program //Get
temperature Double temperature
Double.parseDouble(thermometer.getIndoorTemperatur
e()) if (temperature gt 20) //Turn on
discoBall discoBall.turnOn() //Turn on the
fan fan.turnOn() //Check wind speed Double wind
Double.parseDouble(windMeter.getWindSpeed()) if
(wind gt 2) //Flash the light three
times light.flash(Short.parseShort("3")) //Tur
n off the fan and discoball discoBall.turnOff() f
an.turnOff()

6. View Application when Executing
http//hydra.cnet.se

• Run the application (Run -gt Java Application)
• Check that everything is working in the live
  webcam
