Overview of this book

The initial part guides the reader through the features of DWR and how it works to make the developer ready for practical implementation. The later part contains plenty of code (with explanations) and graphical interface-driven step-by-step examples, which the reader can try out while surfing through the book to learn by doing. This book is written for competent Java developers and assumes that you are a professional rather than hobbyist. You should be familiar with the concepts of programming, Web 2.0, and AJAX.

Summary

This chapter provided samples for a couple of common tasks that are used in web development: tables and lists, field completion, and even a generic frame, called a dynamic user interface, for our sample code. Both the tables and lists sample and the field completion sample had a very simple CSV-based "database" that holds the data for our purposes, and both had a remoted method that DWR uses to get the data from the server and show it in the client.

We also saw some good examples of HTML, CSS, and JavaScript. In fact, without knowledge of JavaScript it would be difficult to write web applications.

Many years ago, as some of you may remember, JavaScript was a dirty word in web development and no self-respecting developer would touch JavaScript. But change is a part of life, and in this case, change has been for the better. JavaScript and Java work very well together with the DWR in between.

The next chapter continues with the user interface part, and shows a couple more samples, including...
