Web App Frameworks - Jakarta Tapestry 4.0-beta-13 released

Tapestry is a component based web application framework that provides lots of functionality with minimal Java coding, and creates an environment that supports high levels of reuse. This release fixed problems with client-side JavaScript for several components. The request cycle object is now an injectable service, and the signatures of several methods in several interfaces were changed to remove it. In addition, a new facility was added that allows services to report their internal state as part of the default Exception page.
