The Jakarta Tapestry web application framework is a comprehensive, component-based approach to building web applications: Java applications that truly execute on the Web. Tapestry allows you to develop a web application without thinking in terms of HTTP or the Java Servlet API. Instead, you stay focused on objects, methods, and properties specific to your application, and the framework provides the low-level plumbing to fit everything together. Building web applications with Tapestry is addictive...and fun!

In this session, we'll assemble several simple web applications, starting with basic HTML files and adding Tapestry instrumentations. Along the way, we'll see a glimpse into how Tapestry improves the whole cycle of web application developer, with a focus on developer productivity. In Tapestry, less is more--less Java code results in more productivity and greater robustness.

We'll see how Tapestry allows HTML forms to be assembled, including forms with server-side and client-side input validation. We'll so how Tapestry keeps the HTML templates clean and WYSIWYG previewable – without the need for specialized tools. We'll see how Tapestry identifies errors and points you directly to the line to be fixed.

We'll also get a glimpse into how Tapestry's component-based approach allows for true reuse of code within and between applications, as well as how Tapestry addresses the needs of large development teams with diverse skill sets.
