EJB Design Patterns
A lot of programming involves solving the same kinds of basic problems. Well, what if a community of experts got together and pooled their knowledge to come up with the best programming practices for solving these problems? You would have what are known as design patterns. Author Floyd Marinescu, a leading expert on EJB, worked with the members of the EJB community of TheServerSide.com to put their collective knowledge together to build a library of design patterns, strategies, and best practices for EJB design and development. This treasure-trove of proven best practices will allow developers to quickly solve difficult programming assignments. Unlike other patterns books, this book goes beyond high-level designs to the actual code for implementing them, saving developers countless hours of time and effort when building scalable, reliable, and maintainable EJB systems.
Mastering Enterprise JavaBeans
Includes more than 30 percent revised material and five new chapters, covering the new 2.1 features such as EJB Timer Service and JMS as well as the latest open source Java solutions The book was developed as part of TheServerSide.com online EJB community, ensuring a built-in audience Demonstrates how to build an EJB system, program with EJB, adopt best practices, and harness advanced EJB concepts and techniques, including transactions, persistence, clustering, integration, and performance optimization Offers practical guidance on when not to use EJB and how to use simpler, less costly open source technologies in place of or in conjunction with EJB

Floyd Marinescu, expert renommé en EJB (Entreprise java Beans, Sun MicroSystems), a travaillé de concert avec les membres de la communauté EJB afin de compiler un savoir collectif et jusqu'ici largement informel au sein d'une bibliothèque de modèles de conception (design patterns). Cet ouvrage dépasse la simple problématique de la conception pour aborder les aspects les plus critiques de l'implémentation. Illustré par du code source, le livre présente un ensemble de vingt modèles EJB explicités, des règles d'or de conception et de développement J2EE, des stratégies d'implémentation, des astuces techniques... On trouvera notamment les notions d'architecture, de transaction, de client, de concurrence, de clé primaire ; des conseils sur les outils Ant, de test JUnit, et l'utilisation des JDO (Java Data Object) comme alternative aux beans d'entité. Ce livre outil offre un réel gain de temps et d'effort aux développeurs aux prises avec la réalisation de systèmes EJB sûrs, dimensionnables et maintenables.
