Owm requires an API key

[mcicolella]

Since Oct 19 an API key is required. http://openweathermap.org/news/post/api-key

Now your library doesn't work. Thanks

You can get an API key for free here: http://openweathermap.org/appid. To construct OpenWeatherMap using the key you received, use:

OpenWeatherMap OWM = OpenWeatherMap(String apiKey);
