Predictive weather mashup exercise

[kkabak]

Hello,

I am having trouble with the 2 services which get the weather information from open weather and yahoo weather site. I have implemented them just like in the tutorials, but I´m receiving the following error codes:

[context: com.thingworx.webservices.context.HttpExecutionContext@511e1e46][message: Execution error in service script [WeatherThing GetYahooWeatherInformation] : Wrapped org.xml.sax.SAXParseException; lineNumber: 1; columnNumber: 1; Content is not allowed in prolog. Cause: Content is not allowed in prolog.]

[context: com.thingworx.webservices.context.HttpExecutionContext@6b492dd3][message: Execution error in service script [WeatherThing GetOpenWeatherForecastData] : Wrapped java.net.MalformedURLException: no protocol: api.openweathermap.org/data/2.5/weather?lat=39.0&lon=-111.0&units=imperial&type=accurate&mode=xml Cause: no protocol: api.openweathermap.org/data/2.5/weather?lat=39.0&lon=-111.0&units=imperial&type=accurate&mode=xml]

Can you please advise?

Two days ago the services were functional and I did not change anything.

Enclosed you can find the project files.

Thank you,

Hi,

The Open Weather API requires an API Key now. You can create yourself one at this website or you can use one that I have created for test  4abc8a3c9f101ccf9c7cfe7cbf3dfed7.

You need to append  &APPID=4abc8a3c9f101ccf9c7cfe7cbf3dfed7 (or your own api key value) at the end of the Open Weather URL in  the GetYahooWeatherInformation service at line 97

   var params = {

url: "http://api.openweathermap.org/data/2.5/weather?q="+cityName+"&type=accurate&mode=xml&APPID=4abc8a3c9f101ccf9c7cfe7cbf3dfed7"

/* STRING */,

timeout: 60 /* NUMBER */

};

And in the GetOpenWeatherForecastData; service at line 6

var params = {

url: "http://api.openweathermap.org/data/2.5/forecast?lat="+lat+"&lon="+long+"&units=imperial&type=accurate&mode=xml&APPID=4abc8a3c9f101ccf9c7cfe7cbf3dfed7" /* STRING */,

timeout: 160 /* NUMBER */

};

You shouldn't have any more errors now.

Hi Vinay,

Please note that yahoo weather api is no longer in service. Please check the post below for a working implementation of the OpenWeatherMap API service call :
