Rod Johnson believes that the matter lies no longer in J2EE itself, yet in that it is usually used badly. Many J2EE guides suggest techniques that, whereas superb in conception, usually fail in truth, or carry no actual enterprise worth.
Expert One-on-One: J2EE layout and improvement aims to demystify J2EE improvement. utilizing a realistic concentration, it exhibits how you can use J2EE applied sciences to lessen, instead of raise, complexity. Rod attracts on his event of designing profitable high-volume J2EE purposes and salvaging failing initiatives, in addition to intimate wisdom of the J2EE necessities, to provide a real-world, how-to consultant on the way you can also make J2EE paintings in perform.
It might help you to resolve universal issues of J2EE and stay away from the pricy error frequently made in J2EE.

Sample text
Using EJB – a technology, which should really be an implementation choice – to drive overall design is risky. In EJB Design Patterns from Wiley(ISBN: 0-471-208310), for example, four of the six "EJB layer architectural patterns" are not true patterns, but workarounds for problems that are introduced by using EJB with remote interfaces. (The Session Façade pattern strives to minimize the number of network round trips, the result being a session bean with a coarse-grained interface. Interface granularity should really be dictated by normal object design considerations.
Middle tier components benefit most from J2EE container services such as transaction management and connection pooling. Middle-tier components are independent of the chosen user interface. If we use EJB, we split the middle tier into two: EJBs, and objects that use the EJBs to support the interface. However, this split isn't necessary to ensure a clean middle tier. 27 Chapter 1 User Interface (UI) Tier This tier exposes the middle-tier business objects to users. In web applications, the UI tier consists of servlets, helper classes used by servlets, and view components such as JSP pages.
The Importance of Business Interfaces Many regard EJBs as the core of a J2EE application. In an EJB-centric view of J2EE, session EJBs will expose the application's business logic, while other objects (such as "business delegate" objects in the web tier in the Business Delegate J2EE design pattern) will be defined by their relationship to the EJBs. This assumption, however, elevates a technology (EJB) above OO design considerations. EJB is not the only technology for implementing the middle tier in J2EE applications.
