I have a system like this under Ant 1.1, and we've found it very handy. I wouldn't have bothered if I was just using it for nightly builds, but the build script(s) also deploy the newly built code into a developer's weblogic installation. Thus, one can change one's code in the source tree (in our case Perforce), type 'ant build deploy' in the directory where you changed the code (only building the package or parent package you just changed), and then restart weblogic and test your change. We were thrilled to pieces when it worked, as it saved people from scary and error-prone file-copying exercises.

Sometime when I don't have a deadline smacking me around the room, I'll post an in-depth description if people are interested.
