Apache Tapestry is an open-source component-oriented Java web application framework conceptually similar to JavaServer Faces and Apache Wicket. Tapestry was created by Howard Lewis Ship, and was adopted by the Apache Software Foundation as a top-level project in 2006.
Tapestry emphasizes simplicity, ease of use, and developer productivity. It adheres to the Convention over Configuration paradigm, eliminating almost all XML configuration. Tapestry uses a modular approach to web development, by having a strong binding between each user interface component (object) on the web page and its corresponding Java class. This component-based architecture borrows many ideas from WebObjects.
A minimal, templated Tapestry application needs only three files:
Tapestry uses bytecode manipulation to transform page and component classes at runtime. This approach allows the page and component classes to be written as simple POJOs, with a few naming conventions and annotations potentially triggering substantial additional behavior at class load time. Tapestry versions 5.0, 5.1 and 5.2 used the Javassist bytecode manipulation library. Subsequent versions replaced Javassist with a new bytecode manipulation layer called Plastic that is based on ObjectWeb ASM.
Tapestry 5 versions up through 5.3 bundled the Prototype and script.aculo.us JavaScript frameworks, along with a Tapestry-specific library, so as to support Ajax operations as first-class citizens. Third party modules are available to integrate jQuery instead of, or in addition to, Prototype/Scriptaculous.
