SAXParseException error in predictive weather app (tutorial)

Hi,

I have some problem with this tutorial https://www.thingworx.com/wp-content/uploads/academic-program-predictive-weather-app-step-1-connect-to-yahoo.pdf.

When I call the GetYahooWeatherInformation service I get this error:

  • ERROR - Error in invoking service Things_WeatherThing, GetYahooWeatherInformation, Things, WeatherThing, Services, GetYahooWeatherInformation. Error from the server: "Wrapped org.xml.sax.SAXParseException; lineNumber: 14; columnNumber: 3; Il tipo di elemento "HR" deve terminare con la corrispondente tag finale "</HR>". Cause: Il tipo di elemento "HR" deve terminare con la corrispondente tag finale "</HR>"."

Code GetYahooWeatherInformation :

Hello,

This documentation is outdated. You can no longer use woeid with yahoo weather apps unless you are paying for an account with them (and even then I am not sure how much of that api is deprecated now). I recommend using Weather Underground (a.k.a. Wunderground).

You can find this documented on the PTC support sit here.

Hope this helps!

Tori
