That log information came from the Windows service wrapper, I think. Can you search in the XAS log for something like this:
2010-03-24 11:20:03.249 INFO - EXTERNALINTERFACE: Starting Jetty 2010-03-24 11:20:03.485 INFO - EXTERNALINTERFACE: Listener will try to use TCP port ????. ... 2010-03-24 11:20:05.790::INFO: Started SelectChannelConnector@0.0.0.0:????
Then you can see which port is being used.
Did you try http://localhost:8009/index.html or http://localhost:8009/login.html ? (or one of the other pages in the web/ folder)
It might be the case that your application is running correctly, but that "/" (as in http://localhost:8009/<nothing>) is not properly redirected to an actual page by your web server.
