1. The rss component, which is implemented by RssPollingComponent class, uses customEditorConfigurer bean to parse the Date variable lastPolledDate into the specified format (yyyy/MMM/dd). lastPolledDate will be used to determine the new items added on the RSS feed.
2. The rss component periodically polls RSS feeds defined on its urlStrings property for changes. In this case rss component monitors the following RSS feeds: http://rss.cnn.com/rss/cnn_topstories.rss^{Image Removed} and http://newsrss.bbc.co.uk/rss/newsonline_uk_edition/front_page/rss.xml^{Image Removed}.
3. 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.
4. The trace component displays the RSS news items on the console.

http://docs.codehaus.org/x/3XM^{Image Removed}We support working with RSS and Atom via the Rome library. We support both the polling of existing RSS feeds to generate JBI messages (the example documented above) and the generation of RSS feeds from JBI messages. To see an example of how to generate RSS feeds from JBI messages go here.
