The sneaky way to do this is to use a META REDIRECT.
I had the same issue. I wanted a domain name (www.mydomain.com) to resolve right down to a certain page.
But the only page that is served with nothing but the domain typed in is 'index.html'
So all you need to do is re-write Tomcat's index.html to do something like this:
So now, when you type
www.mydomain.com, Tomcat will serve the 'default' index.html page from it's webapps/ROOT directory.
But you've re-written that page to tell the browser to immediately refresh to the page you really want them to see.
