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.

overlayContext.xml
 <!--  worldweatheronline.com Weather DAO Implementation  -->

 <!--
 <bean id="weatherDaoImpl" class="org.jasig.portlet.weather.dao.worldwide.WorldWeatherOnlineDaoImpl">
 <property name="key" value="YOURKEY"/>
 <property name="imageMapping"><value>classpath:wwo-image-mapping.properties</value></property>
 </bean>
 -->

 <!--  Yahoo! Weather DAO Implementation  -->

 <bean id="weatherDaoImpl" class="org.jasig.portlet.weather.dao.yahoo.YahooWeatherDaoImpl">
 <property name="key" value=""/> <!-- ENTER YOUR KEY HERE -->
 <property name="weatherParsingService" ref="weatherParsingService"/>
 <property name="locationParsingService" ref="locationParsingService"/>
 <property name="messageSource" ref="messageSource"/>
 </bean>
