Eclipse comes in various flavors, and includes a reasonable XML editor built-in. It can be downloaded from the eclipse.org web site. We recommend the latest version of Eclipse IDE for Java Developers (but anything from version 3.7 onward should work fine).

Jetty

Jetty is an open source web servlet and servlet container available from the Eclipse Foundation. Jetty is designed for high performance and easy embedding in other software.

RunJettyRun Eclipse Plugin

RunJettyRun is a very simple Eclipse plugin that bundles a version of Jetty (Jetty 6 at this writing) so that you can create Eclipse launches that start Jetty to execute your web application.

You can install RunJettyRun using Eclipse's Install New Software... menu item; the update URL is http://run-jetty-run.googlecode.com/svn/trunk/updatesite.

This tutorial was written with RunJettyRun version 1.3.1.

Apache Maven 3

Maven is a comprehensive software build tool with the ability to automatically download project dependencies (such as the Tapestry JAR files, and the JAR files that Tapestry itself depends on) from one of several central repositories.

Maven is not essential for using Tapestry, but is especially helpful when performing the initial set-up of a Tapestry application.

Eclipse comes with its own a Maven plugin, M2Eclipse (also known as m2e) that you are free to use if you're already familiar with it. However, for this tutorial we'll use the Maven command line ("mvn"). The command-line version of Maven is available with an embedded version of Maven. We'll use that here for simplicity's sake. Alternatively, you could install Maven from http://maven.apache.org/download.html. Go ahead and download and install it and use it from the command line ("mvn").

Jetty

Jetty is an open source web server and servlet container available from the Eclipse Foundation. Jetty is designed for high performance and easy embedding in other software. Maven can download it for you and run it automatically, so you DO NOT have to download it for this tutorial. Alternatively, you could download and install the RunJettyRun Eclipse plugin from the Eclipse Marketplace.

Tapestry

You should not have to download this directly; as we'll see, Maven should take care of downloading Tapestry, and its dependencies, as needed.
