GTFS Realtime

To add support for GTFS-Realtime, make sure your graph is built with TransitIndexBuilder and add the following to your application-context.xml in opentripplanner-api-webapp:

<bean id="periodicGraphUpdater" class="org.opentripplanner.api.servlet.PeriodicGraphUpdater">
    <property name="updaters">
        <list>
            <bean class="org.opentripplanner.updater.GtfsRealtimeUpdater">
                <property name="url" value="YOUR URL" />
                <property name="defaultAgencyId" value="YOUR AGENCY ID" />
            </bean>
       </list>
   </property>
</bean>

In master branch (current unstable) this is configured in Graph.properties file. More information about this type of configuration is available on page about Graph Updaters.
