I've changed tapestry-spring to be simpler and better. It now leverages Spring's ContextLoaderListener, rather than trying to replace it. In addition, it is now compiled for compatibility with JDK 1.3.
Since it is so alpha, I haven't been bumping up the version number for these changes. I suspect a 1.0.0 release will come soon. This library is now down to one class, some XML configuration, and a little bit of test code.
