Congratulations !!!! 2006/1/8, Jean-Philippe Bouchard <[EMAIL PROTECTED]>: > Congratulations to Howard and everybody involved! > > I've migrated my site recently to 4.0-rc2 (in order to get non-ugly > urls) and the migration was virtually painless. > > Well done! > > Ciao > JPB > > Howard Lewis Ship wrote: > > After nearly two years of work, the Tapestry development team is proud > > to announce the next major release of the Tapestry web application > > framework (http://jakarta.apache.org/tapestry/). > > > > Tapestry is an open-source framework for creating dynamic, robust, > > highly scalable web applications in Java.

This makes it > > easy to divide your application across many folders (reducing > > clutter), and leverage J2EE declarative security along the way. > > * Listener methods are much easier and more flexible; listener > > parameters in the URL are automatically mapped to listener method > > parameters, and listener methods can return the page name or page > > instance to activate. > > * Component parameters now just work, without having to worry > > about "direction". > > * Applications can now have a global message catalog, in addition > > to per-page and per-component message catalogs.
