pure Java code surrounded by HTML. This coupling becomes problematic for both Java developers and HTML designers. Finally, developers realize that an old true-and-tried architectural pattern, the Model-ViewController (MVC), was the solution to the problem of scaling and maintaining Web applications. The MVC pattern separates the data (model) from the presentation (view) and the work flow (controller). In Model 2 architectures, JSP and servlets were used in combination and taking advantage of their respective strengths. Servlets are used to dispatch the views and glue (and maybe transform) data coming from a back end such as a database or EJBs. This is the controller part of the MVC pattern providing application flow and service and resource discovery and allocation for the view generation technology, the JSP pages. JSP/Servlet Model 2 represented a huge leap forward in terms of maintainability and development time. It allowed for separation of concerns between HTML designers and Java developers as well as between Java developers of varied skills; more-seasoned developers usually ended up writing most of the controlling code while more-junior developers deal with the JSPs. As more and more Model 2 applications were being built, many developers noticed the repetition of effort from application to application. The typical question became, how do we avoid recreating the wheel over and over again And most developers conclusion culminated with the creation of frameworks to provide uniform ways to deal with MVC applications and removing the need for the plumbing code. Today we have many frameworks based on the MVC pattern, and they provided a great deal of functionality that you no longer have to create from scratch. They also standardized Web development in the Java world to an extent. The different frameworks all implement MVC in slightly different ways. Some have one chosen technology for view generation such as JSPs or some sort of template engine as Velocity, while others allow pluggable view implementations. One thing that most have in common is that although they are built on top of the servlet API, they still work under the same underlying principle of the request/response paradigm that makes your development and the resulting code very procedural. Many technologists feelings were these frameworks help us deal with the Web as an application platform, but they have also flattened and taken away some of the power of object orientation provided by Java. Meanwhile, a little-known framework was already providing a framework for Web development based on the MVC pattern but with components that embraced object-orientation at its core. That framework was NeXT WebObjects, which appeared in 1996 and later became Apple s WebObjects. WebObjects had a great deal of interest behind it and attracted a significant number of large players looking for a robust platform on which to build large-scale Web applications. WebObjects today remains a closed source proprietary system that until just recently had a price tag that placed it out of most developers hands. WebObjects is a J2EEcompliant Web development framework providing more than just Web development a suite of tools, advanced ORM, scalability, and performance features. For example, one of the largest applications running on WebObjects is Apple s iTunes Music Store. Fortunately for most of us, an alternative as powerful and flexible as WebObjects is available from the open source community in the Jakarta Tapestry Web application framework. Tapestry began life as a SourceForge project in 2000 loosely based on the way WebObjects worked. It gained enough public acceptance to become an Apache Jakarta project in 2003.

Tapestry is an open source Java Web application framework created by Howard Lewis-Ship and a talented group of contributors. Tapestry is distributed under the Apache Software License version 2.0. In Tapestry, as opposed to other frameworks like Struts, you deal with components and pages (which are themselves components), and interactivity is provided via listeners which interpret the user s actions associated with a component. A Tapestry application is made of pages. Each page consists of a template and a number of components. The templates are standard HTML pages decorated with span tags declaring the Tapestry components. Tapestry is built on top of the servlet API, but unlike other frameworks, it completely abstracts the procedural request-response nature of the Web by allowing you to work with pages and components in a similar way that a Java Swing developer works with forms and components. As with many Web frameworks, Tapestry takes the drudgery out of common tasks and functionality like state management, input validation, localization and internationalization, and error reporting. But instead of dealing with URLs, HTTP requests, and responses, you work at a higher level of abstraction dealing with user interaction with the pages and components in an object-oriented way. As in a Swing application, components and pages know how to respond to events which are mapped from the HTML component view representation to the Java implementation. One of the greatest strengths of Tapestry for a Web development team lies in its strong separation of concerns between Web designers and Java developers. It also brings true objectoriented development to Web applications. As a former Delphi and Swing developer, I was initially attracted to experiment with Tapestry by this factor. In Tapestry you create plain HTML pages, and using span tags or any other HTML tags, you embed Tapestry components. Tapestry allows you to use static markup in the location of the components to accurately represent the look and feel of the page at design time. These static placeholders (for example, a drop-down field) are replaced at runtime with a live Tapestry component. This allows HTML designers to work with the actual templates used by the application, guaranteeing that the responsibility for the application look stays with the designers and functionality stays with the application developers. The components view in the HTML and any possible actions taken by a user on a component are glued together with small amounts of Java code and optionally with very simple XML configuration files. Tapestry uses the HiveMind IoC framework/microkernel under the covers to deal with resource and service configuration. We will learn more about HiveMind as we work to integrate a Tapestry Web application with an EJB3 back end. Tapestry also comes with a large collection of prepackaged components, provides good support for JavaScript (for clientside validation and interaction) and has several third-party libraries that provide AJAX-enabled components. Tapestry is a battle-tested Web framework that can be used to create scalable and robust Web applications.
