Explore J2EE Antipatterns

ature provides us with an infinite variety of patterns, from those found in living things: in the foliage of plants, for example, or in the structure of plants themselves, and in animals—to those created by the actions of physical laws: the formation of crystals, or ripples on a pond. It's not surprising therefore that architects—of buildings or software—follow nature's example by making use of patterns in their own creations.

J2EE Design Patterns explores the patterns that underlie effective software designs. As Crawford and Kaplan explain, a design pattern is a way of describing recurring solutions to common, recurring problems. From a programming perspective, they say, "a pattern provides a set of specific interactions that can be applied to generic objects to solve a known problem."

Many of the patterns in this book focus on extensibility, scalability, flexibility, and performance--all areas of concern to J2EE developers. Some patterns will be new to readers and some will be familiar. But whether readers have seen the patterns before or not, "J2EE Design Patterns" is unique in showing readers how to apply them in real J2EE applications.

Chapter 12 discusses the causes of antipatterns, architectural antipatterns, presentation tier antipatterns, and EJB antipatterns.
