I'm not referencing any particular framework, but Rails is an example. Recently the Rails team has done a lot to modularize it too though.
are you using maven, etc.? I would be very interested to find out how a ruby centric dev shop is handling Java deployments and builds.
P. S. how about mocks and testing?
Personally, I can't begin to describe the awfulness of Maven in words. I'd sooner use makefiles and shell scripts, or manually type in build commands written in pen on a stack of notecards.
But you don't have to take my word for it; here's an SO discussion about how much Maven sucks:

Most projects use Junit and Easymock.
I'll see if I have some time to write a blogpost about it.
