Looks like you are running on a Mac. Please post the contents of your /etc/hosts file, and perhaps someone who runs on a Mac can point out if there are any issues with it (if it was Linux I could probably spot the error).
Never mind. I got it working.
I apparently needed to set autoDeploy="true" and deployOnStartup="true".
Furthermore, my expanded web application directory needed a war extension, or I got INIT_WAITING_DEPLOYER errors.
Thanks, PeterJ, for the reply (my post above was made before seeing your note).
