Messages flow through the components as follows:
- The rss component, which is implemented by RssPollingComponent class, periodically polls RSS feeds defined on its
urlStringsproperty for changes. In this case rss component monitors the following RSS feeds: http://rss.cnn.com/rss/cnn_topstories.rss
and http://newsrss.bbc.co.uk/rss/newsonline_uk_edition/front_page/rss.xml. - When an update is found, the rss component creates a normalized message that contains the new items. It then sends the normalized message to the NMR. The NMR routes the message to the trace component.
- The trace component displays the new RSS news items on the console.
Typical output looks like the following:
