Messages flow through the components as follows:
- HttpClient, a Java stand-alone program, connects to rss component implemented by RssPollingComponent class polls RSS feeds defined on its urlStrings property. In this case rss component monitors http://localhost:8912
through the URLConnection class. HttpClient sends the file request.xmlto this port.httpReceiver, an HTTP server, being a listener on rss.cnn.com/rss/cnn_topstories.rss and http://localhost:8912 receives the message. - httpReceiver sends the message to stockQuote as specified in its destinationService property, via NMR.
- stockQuote sends the message into another service, soapEndpoint for processing.
- soapEndpoint sends the response to stockQuote.
- stockQuote sends the response to httpReceiver via NMR.
- httpReceiver sends the response to http://localhost:8912.
- HttpClient reads the response.
- The response is printed on the console.
