Weather Portlet Configuration

Weather Providers

The weather portlet ships with two different weather data providers, Yahoo Weather and World Weather Online. Both services require an API key which can be retrieved by a self-service registration process.

Yahoo Weather

• Update 3/15/2016:  Portlet must change to support Oath 1.  See https://developer.yahoo.com/weather/.
• ToC limits usage to non-commercial use
• Key only required for location lookups
• 2000 invocations per day (Weather portlet caching reduces invocations per day)
• Much nicer icons
• Provides forecasts only two days into the future
• API key requests at https://developer.apps.yahoo.com (log in and select My Projects from your avitar image on top right)

World Weather Online

• Update 3/29/2016:  They no longer offer a free API key to new users.
• Free to both non-commercial and commercial users
• Requires a key for both weather and location lookups
• Requires 15 minute caching of each feed (already the weather portlet's default caching strategy)
• Limit of 500 requests / hour
• Provides forecasts several days into the future (configurable)
• API key requests at http://www.worldweatheronline.com/register.aspx

Configuring the Provider

Maven Overlay

The weather portlet has been included in uPortal since 3.2 via an overlay as src/main/webapp/WEB-INF/context/overlay/overlayContext.xml.  This old file exists but the configuration has been moved to src/main/webapp/WEB-INF/context/applicationContext.xml.

Un-comment the provider you want to use in the applicationContext.xml file and specify the API key for the service.
