Practical DWR 2 Projects

The Ajax craze is sweeping the world, and there is no shortage of libraries from which to choose to make it all easier to develop. One of those libraries has risen near the top in the Java space, and that library is DWR. DWR, or Direct Web Remoting, allows you to treat your Java classes running on the server as if they were local objects running in the browser, bringing the full power of your server–side business logic to the client without the usual problems that entails. In this book, you will:

• Explore DWR and all it offers
• Find six full, working applications that use DWR, instead of a lot of theoretical musings
• Learn by example, more importantly, by doing, as you tear the applications apart, see what makes them tick, and even extend them at your own pace

In the end, you’ll have a great feel for what DWR offers and how Ajax can bring the world of Web 2.0 to your doorstep, and you’ll have a good time doing it.

What you’ll learn

• Call a server–side object in a snap and make it look like any local JavaScript call to boot
• Provide a strong security mechanism for securing your server-side code
• Integrate with many of the most popular frameworks out there
• Provide not only Ajax but Comet capabilities (sometimes called reverse Ajax)
• Dig into Ajax using DWR in a practical and hacking kind of way starting with a webmail client and Wiki projects
• Build a simple file manager application and an online timesheet system
• Complete a DWR–based game project

Web application developers, senior projects leads, and application architects.

The Ajax craze is sweeping the world, and there is no shortage of libraries from which to choose to make it all easier to develop. One of those libraries has risen near the top in the Java space, and that library is DWR. DWR, or Direct Web Remoting, is an Ajax library and Web framework that is very popular, and getting backing and support from Spring Framework developers and users.

Practical DWR Web 2.0 Projects addresses the needs of most developers who would rather learn by example and by doing. This book contains several projects that developers can sink their teeth into doing.

Written by accomplished Ajax and Java Web developer and author, Frank Zammetti, this book looks to be first and only book on this popular Ajax and Web development technology to market.

Frank W. Zammetti is a web architect specialist for a leading worldwide financial company by day, and a PocketPC and open-source developer by night. He is the founder and chief software architect of Omnytex Technologies, a PocketPC development house.

He has over 12 years of "professional" experience in the IT field, and over 12 more of "amateur" experience. He began his nearly life-long love of computers at age 7 when he became one of four students chosen to take part in the school district's pilot computer program. A year later, he was the only participant left! The first computer Frank owned was a Timex Sinclair 1000 in 1982, on which he wrote a program to look up movie times for all of Long Island (and without the 16k expansion module!). After that, he moved on to a Commodore 64 and spent about 4 years doing nothing but assembly programming (games mostly). He finally got his first IBM-compatible PC in 1987, and began learning the finer points of programming (as they existed at that time!).

Frank has primarily developed web-based applications for about 8 years. Before that, he developed Windows-based client/server applications in a variety of languages. Frank holds numerous certifications including SCJP, MCSD, CNA, i-Net+, A+, CIW, MCP, and numerous BrainBench certifications. He is a contributor to a number of open source projects, including DataVision, Struts, PocketFrog, and Jakarta Commons. In addition, Frank has started two projects: Java Web Parts and The Struts Web Services Enablement Project. He also was one of the founding members of a project that created the first fully functioning Commodore 64 emulator for PocketPC devices (PocketHobbit).

Frank has authored various articles on topics that range from integrating DataVision into web apps, to using Ajax in Struts-based applications. He is currently working on a new application framework specifically geared to creating next-generation web applications.
