Product Description
Sometimes the simplest answer is the best. Many Enterprise Java developers, accustomed to dealing with Java's spiraling complexity, have fallen into the habit of choosing overly complicated solutions to problems when simpler options are available. Building server applications with "heavyweight" Java-based architectures, such as WebLogic, JBoss, and WebSphere, can be costly and cumbersome. When you've reached the point where you spend more time writing code to support your chosen framework than to solve your actual problems, it's time to think in terms of simplicity. In Better, Faster, Lighter Java, authors Bruce Tate and Justin Gehtland argue that the old heavyweight architectures are unwieldy, complicated, and contribute to slow and buggy application code. As an alternative means for building better applications, the authors present two "lightweight" open source architectures: Hibernate--a persistence framework that does its job with a minimal API and gets out of the way, and Spring--a container that's not invasive, heavy or complicated. Hibernate and Spring are designed to be fairly simple to learn and use, and place reasonable demands on system resources. Better, Faster, Lighter Java shows you how they can help you create enterprise applications that are easier to maintain, write, and debug, and are ultimately much faster. Written for intermediate to advanced Java developers, Better, Faster, Lighter Java, offers fresh ideas--often unorthodox--to help you rethink the way you work, and techniques and principles you'll use to build simpler applications. You'll learn to spend more time on what's important. When you're finished with this book, you'll find that your Java is better, faster, and lighter than ever before.
About The Author
Bruce A. Tate is a kayaker, mountain biker, and father of two. In his spare time, he is an independent consultant in Austin, Texas. In 2001, he founded J2Life, LLC, a consulting firm that specializes in Java persistence frameworks and lightweight development methods. His customers have included FedEx, Great West Life, TheServerSide, and BEA. He speaks at conferences and Java user's groups around the nation. Before striking out on his own, Bruce spent 13 years at IBM working on database technologies, object-oriented infrastructure, and Java. He was recruited away from IBM to help start the client services practice in an Austin startup called Pervado Systems. He later served a brief stint as CTO of IronGrid, which built nimble Java performance tools. Bruce is the author of four books, including the bestselling Bitter Java, and the recently released Better, Faster, Lighter Java, from O'Reilly. First rule of kayak: When in doubt, paddle like Hell.
Working as a professional programmer, instructor, speaker and pundit since 1992, Justin Gehtland has developed real-world applications using VB, COM, .NET, Java, Perl and a slew of obscure technologies since relegated to the trash heap of technical history. His focus has historically been on "connected" applications, which of course has led him down the COM+, ASP/ASP.NET and JSP roads. Justin is the co-author of Effective Visual Basic (Addison Wesley, 2001) and Windows Forms Programming in Visual Basic .NET (Addison Wesley, 2003). He is currently the regular Agility columnist on The Server Side .NET, and works as a consultant through his company Relevance, LLC in addition to teaching for DevelopMentor.
Customer Reviews & Comments
This book delivers a great message in the worst possible way. It is useful if you are trying to persuade a PHB (management) that going with a full-blown EJB solution doesn't make sense. If you need to convince an architect about this, give them Rod Johnson's book "Expert one-on-one J2EE Design and Development without EJB". If you want to actually learn anything about the approach and philosophy, don't use this book. For one thing, the authors are working on a broken definition of "coupling" and fail to address "cohesion" by its proper name. In short, there is a lack of depth and rigor in what they are presenting that, at times, leads them to recommend approaches that aren't necessarily valid. For example: Using a message passing API without a strict message format definition (such as a WSDL definition in the WS world) actually leads to tighter coupling because the author of a service client must inspect the code of the service in order to understand the rules of exchange (the API). By definition that is tight coupling. The omission is minor, but significant in understanding the pitfalls of message-oriented service integration. In short, AOP and related ideas are all about cohesion. Not just on the function or method level, but on the interface and class level. "Separation of concerns" sounds a lot like "functional cohesion". Not addressing this well understood issue by its formal name denies the reader the opportunity to find the broader body of knowledge on the subject. Why reinvent the wheel? I guess if I had to sum up why this book isn't worth your money is because it is dogmatic and not prescriptive. The great thing about Rod Johnson's book is that it tells you not only when it is appropriate to take this approach, but the different ways to do so. The examples presented here are straw-men and "hello world" (as described above). What would be nice is a full example that brings all the pieces together. An implementation of the Java Pet Store using this approach, fully described point-by-point would be a nice approach.
