Java Web App Call Stack

Peter Thomas has posted a screen grab of a call stack from the initial HTTP call through to the JDBC access.

What's interesting is that the actual business logic is just a tiny portion of what's going on, which fits nicely with my experience with well-designed applications (read: "apps I've designed"). There's a lot of infrastructure involved that has nothing to do with the specifics of, say, where you want package shipped and what to do if the zip code and the city don't match.

And in any event, it's just kind of pretty to see a bird's eye view of all those frameworks working together so neatly.
