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.


  • 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 (log in and select My Projects from your avitar image on top right)

World Weather Online

  • 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


The weather portlet has been included in uPortal since 3.2 via an overlay .Add as src/main/webapp/WEB-INF/context/overlay/overlayContext.xml file in the overlay project:


.  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 overlayContextapplicationContext.xml file and specify the API key for the service.
