I want users to be able to just go to my domain and reach my web
application without having to include the web app name in the URL.

GOOD:  www.domain.com
BAD:     www.domain.com/myapp

I am not opposed to having myapp in the URLs as they use the site, but
I don't want to force people to type it when they first come to the
site.

I know there are a few ways to do this.

I currently have Tomcat and Glassfish configured so that / is the
context for the app.  This works fine, but it has always seemed like a
hack rather than an accepted process.

Is there a better, more accepted, way of accomplishing this?

Thanks.
