Spring MVC, a part of the core Spring Framework, is a mature and capable action-response style web framework, with a wide range of capabilities and options aimed at handling a variety of UI-focused and non-UI-focused web tier use cases. All this can potentially be overwhelming to the Spring MVC neophyte. I think it's useful for this audience to show just how little work there is to get a bare Spring MVC application up and running (i.e. consider my example something akin to the world's simplest Spring MVC application), and that's what I'll spend the rest of this article demonstrating.

Possibly the most important thing to watch out for is that this release introduces versioned file/location names for the 2.0 DTD and Schemas (XSDs). This was necessary since the XML bean definition format was significantly enahnced for 2.0, but 1.2.x users still need to be able to refer to the 1.2.8 DTD. Here is an example of using the 2.0 "beans" schema (2.0 ships with a number of other new schemas as well, representing various special namespaces…
