Aspect-oriented software design (ASOD), which follows the Java philosophyof "write once, run anywhere", is a new way of thinking about programconstruction. It is a rapidly growing and evolving programming methodologythat some feel may eventually replace object-orientation as the dominantprogramming paradigm. The first public release of the AspectJ programminglanguage was in 1998 and has been gaining momentum ever since. This book isan introduction to AOP with AspectJ and Eclipse and shows how to create aproductive AO development environment by using the AspectJ DevelopmentTools for Eclipse (AJDT). Tools have an important role to play in learningaspect-orientation (AO) and Eclipse tools help Java developers betterunderstand AOP. In fact the growing interest in AOP can be attributed to thebetter available tools and this book teaches the reader everything they need tounderstand AOP and apply it successfully to their own projects.

About the Authors ADRIAN COLYER is a senior technical staff member at IBM, the leader of the AspectJ Eclipse project, and co-founder of the AspectJ Development Tools (AJDT) for Eclipse project. Currently he leads an IBM team developing and applying aspect-oriented technology. ANDY CLEMENT is a senior software developer at IBM's Laboratory at Hursley Park, a committer on the AspectJ project, and co-founder of the AJDT project. He is also involved in the use of aspects in J2EE middleware. GEORGE HARLEY is a senior developer at IBM's Hursley Laboratory currently working on AJDT and deploying aspect technology in enterprise applications. MATTHEW WEBSTER joined IBM in 1989 and is currently developing aspect-oriented technology for use with IBM products. © Copyright Pearson Education. All rights reserved.
