Apache Tapestry is an open-source framework for creating dynamic, robust, highly scalable web applications in Java or other JVM languages. Tapestry complements and builds upon the standard Java Servlet API, and so it works in any servlet container or application server.
Tapestry is released under the Apache Software License 2.0.
Tapestry has a long history, with the oldest code dating back to January 2000. That means a lot of releases. At this time, Tapestry releases 3 and 4 are no longer being developed; developer effort for the past several years has focused on Tapestry 5.
