Definitive, complete SCEA examination Prep–Straight from Sun’s examination Developers!
This publication gives you entire, targeted evaluation for Sun’s new solar qualified firm Architect (SCEA) for Java EE certification exam–straight from of the exam’s creators! SCEA lead developer/assessor Mark Cade and SCEA lead developer/assessor Humphrey Sheil provide robust insights, real-world architectural case reports, and demanding pattern questions that systematically organize you for the particular examination. for each query, the authors express why the fitting solutions are right–and why the opposite solutions are unsuitable. Cade and Sheil disguise each SCEA examination subject, ability, and process, including:
Understanding process structure and its goals
Decomposing higher platforms into elements geared up by means of stages or layers
Addressing standards for scalability, maintainability, reliability, availability, extensibility, functionality, and security
Building potent internet (presentation) levels, and interpreting tradeoffs linked to utilizing net frameworks
Leveraging EJB 3’s improvements for company tier development
Covering new improvements within the JEE five platform
Choosing and architecting the easiest integration and messaging elements on your system
Using the Java safety version to implement confidentiality, integrity, authorization, authentication, and non-repudiation
Using the main robust and precious Java EE structure patterns
Documenting Java EE architectures via visible versions and narratives
The authors additionally current exact counsel for dealing with each portion of the SCEA exam–including your improvement and security of a whole real-world architectural solution.

Introduce cached copies of data to reduce the computation overhead, as follows: ■ ■ ■ Introduce concurrency to computations that can be executed in parallel. Limit the number of concurrent requests to control the overall system utilization. Introduce intermediate responses to improve the performance perceived by the user. To improve the system throughput, it is common that a timeout is applied to most of the long-lasting operations, especially those involving the access to an external system. Improving Availability The factors that affect the system availability include the following: ■ ■ System downtime—The system downtime can be caused by a failure in hardware, network, server software, and application component.
It is perfectly possible to add tags to a JSP page that represent a speciﬁc JSF UI component, resulting in a hybrid solution. 0 implementations of speciﬁcations in the JEE platform), but it has matured since then. Many architects, however, simply see no need for it and prefer JSP with JSTL and EL. Web-Centric Implementations As intimated earlier, a signiﬁcant proportion (exact ﬁgures are not available and indeed vary by industry vertical) of all JEE applications in existence today are deployed using only a web container—that is, they do not use EJBs.
1 Sun Microsystems, Inc. 34 Chapter 2 Architecture Decomposition Which architecture is most appropriate for your prototype project? A. B. C. D. Three-tier, application-centric Three-tier, enterprise-centric Three-tier, web-centric Two-tier, web-centric Answer: D. Because it is a prototype, you only need two-tiers. This enables you to do it quickly and focus on your part of the system, which is the user interface. 2. A company has an existing system that is a two-tier (presentation/business logic → database) architecture, which requires installation of code on a PC.
