Introduction to Tapestry 4

An introduction to the Apache Tapestry web application framework, which will explain the concepts and features of the framework with some simple applications. We'll discsuss Tapestry forms, request cycle, component object model. The use of several important components, including BeanForm and Table will be highlighted, along with meta-programming using the Trails framework.

Tapestry is a powerful open-source Java web application framework that stands apart from most other technologies used for creating web applications ? it is based on highly reusable components, which are assembled to form complete pages. This session will get you started with Tapestry, showing how to build a simple form-based application. Along the way, we'll see how Tapestry simplifies your job: We'll see how Tapestry HTML templates are easier to create and maintain than JavaServer pages (JSPs). We'll see how Tapestry's built in error reporting lets you find and correct errors with startling speed. We'll see how Tapestry takes over responsibility for building and interpreting application URLs, eliminating large amounts of boring, error-prone, manual coding. Most importantly, we'll see how Tapestry bridges from the stateless world of HTTP and servlets into a more natural, more productive world of actual object oriented engineering ? allowing you to build applications in terms of objects with methods and properties (a true revolution if you are used to traditional servlets).

We'll also take a peek into more advanced aspects of Tapestry, such as its input validation subsystem that provides server- and client-side validation, as well as more advanced Tapestry components such as Table (a powerful data grid), and the Trails meta-framework that creates complete applications without almost no coding. Once you've learned a little bit about Tapestry, you might find it hard to go back to your old approach!
