apache-tapestry Documentation

Some Fossies usage hints in advance:

  1. To see the Doxygen generated documentation please click on one of the items in the steelblue colored "quick index" bar above or use the side panel at the left which displays a hierarchical tree-like index structure and is adjustable in width.
  2. If you want to search for something by keyword rather than browse for it you can use the client side search facility (using Javascript and DHTML) that provides live searching, i.e. the search results are presented and adapted as you type in the Search input field at the top right.
  3. Doxygen doesn't incorporate all member files but just a definable subset (basically the main project source code files that are written in a supported language). So to search and browse all member files you may visit the Fossies
  4. apache-tapestry-5.5.0-sources.zip contents page and use the Fossies standard member browsing features (also with source code highlighting and additionally with optional code folding).
README.md

Tapestry is a component-oriented Java web app framework focusing on performance and developer productivity.

A component is just a reusable part of a page. It's trivially easy to create your own components, and Tapestry comes with a large number of components you can use (Form, Loop, Select, Checkbox, Grid, BeanEditor, etc.).

In Tapestry, each page and component is a simple Java POJO with a corresponding HTML template. The HTML template and corresponding Java class have the same name (e.g. "Breadcrumbs.html" and "Breadcrumbs.java"), so you don't have to tell Tapestry which template uses which Java class. It's automatic.

Tapestry features live class reloading: change your Java code, refresh the browser and see the changes instantly.

AJAX support allows you to create responsive web interfaces while writing little to no JavaScript. (But if you like writing JavaScript, great, no problem, Tapestry gets out of your way.)

Quick Start

Main article: Getting Started

You can let Apache Maven create your initial project for you:

mvn archetype:generate -DarchetypeCatalog=http://tapestry.apache.org

Maven will prompt you for the archetype to create ("Tapestry 5 Quickstart Project") and the exact version number (e.g., "5.4.3"). It also asks you for a group id, an artifact id, and a version number. Once Maven dowloads everything, then you can start the app:

$ cd newapp
$ mvn jetty:run

Then just send your browser to http://localhost:8080/newapp

See the Getting Started introduction as well as the Tapestry Tutorial for a deeper dive.
