Well, as far as J2EE apps go, OpenGrok is a breeze to deploy, but it's still a PITA.
OpenGrok indexing is very very slow. It used to take 10+ minutes on my codebase and my machine. When I switched to Russ Cox' codesearch, indexing was so fast that I just put it in my .profile. And I didn't have to run Tomcat on my laptop.
I haven't tried this tool yet, but if it works by the same principles as codesearch I'd expect it to be very fast.
