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.

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 information technology 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 his 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 working on a new application framework specifically geared to creating next-generation web applications.
