As is usual with pattern books you won't find much code here. The book majors on problem discussions, analysis of the factors you should consider in your design and strategies for the solution implementation.

The authors constantly encourage abstraction, code modularity, non-duplication of code, network efficiency, code maintainability and solution reusability.

While these are the aims we've been encouraged to pursue for years too many pattern books operate at such a high theoretical level they fail to appeal to working programmers. In practice, you could use the patterns discussed with any language but by concentrating on using Java Core J2EE Patterns is able to take a more hands-on approach.

OK, you won't find detail at the level of APIs here, but you will find discussion of where to implement functionality to best leverage Java's architecture and which Java mechanisms to use: for example, implementing entity beans as coarse-grained--rather than fine-grained--objects to reduce the transaction overhead. Not the sort of implementation advice you'll find in language-agnostic pattern books.

Core J2EE Patterns enables you to dramatically cut the design time on enterprise level Java based projects while increasing the likelihood that the project will reach a timely fruition. --Steve Patient

Product Description

Sun Microsystems' Java 2 Platform, Enterprise Edition (J2EE) has become the platform of choice for Web-centric distributed enterprise application development. Expert consultants from the Sun Java Center have been helping customers build J2EE-based solutions since the earliest days of the technology, focusing primarily on up-front design and architecture. Along the way, they've identified powerful J2EE design patterns that lead to applications with superior performance, scalability, and robustness. This book brings those design patterns together, sharing Sun's best practices for development with Java Server Pages (JSP), Servlets, EJB, and other J2EE technologies. It presents a complete catalog of J2EE patterns encapsulating proven and recommended designs for common J2EE-related problems, organized into presentation tier, business tier and integration tier solutions. Presentation tier patterns describe solutions involving JSP and servlets; business tier patterns describe solutions involving EJB; and integration tier patterns describe solutions involving JDBC and Java Messaging Service (JMS). The book also identifies bad practices to be avoided. Finally, it presents an end-to-end multi-tier case study covering every stage of enterprise development.
