Apache Struts 2 Web Application Development

In DetailStruts 2.1 is a modern, extensible, agile web application framework suitable for both small- and large-scale web applications.The book begins with a comprehensive look at Struts 2.1 basics, interspersed with detours into more advanced development topics. You'll learn about configuring Struts 2.1 actions, results, and interceptors via both XML and Java annotations. You'll get an introduction to most of the Struts 2.1 custom tags and learn how they can assist in rapid application prototyping and development.From there you'll make your way into Struts 2.1's strong support for form validation and type conversion, which allows you to treat your form values as domain objects without cluttering your code. A look at Struts 2.1's interceptors is the final piece of the Struts 2.1 puzzle, allowing you to leverage the standard Struts 2 interceptors as well as implement your own custom behavior.After covering Struts 2.1 you'll journey into the world of JavaScript, a surprisingly capable language, the Document Object Model (DOM), and CSS, and learn how to create clean and concise client-side behavior. You'll leverage that knowledge as you move on to Struts 2 themes and templates, which give you a powerful way to encapsulate site-wide user interface behavior.The book closes with a look at some tools that make the application development life cycle easier to manage, particularly in a team environment, and more automatic.This book provides an in-depth introduction to Struts 2 and crash-courses in JavaScript, CSS, Test-Driven Development, agile programming techniques, and tool development, focusing on the delivery of complete, documented, maintainable web applications.ApproachThis book takes a clear approach, focusing on one topic per chapter, but interspersing other issues in the mainline text and in chapter detours. Taking a practical approach, it discusses agile web development using Struts 2, with plenty of examples for better understanding.Who this book is forThis book is for Java developers who are interested in developing web applications using Struts.
