| SINCE its introduction more than two years ago, the Java 2 Platform, Enterprise Edition (J2EE), has rapidly established a new model for developing distributed applications. This model is based on well-defined components that can automatically take advantage of sophisticated platform services. These components can be developed according to standard guidelines, combined into applications, deployed on a variety of compatible server products, and reused for maximum programmer productivity. This model is intended to both standardize and simplify the kind of distributed applications required for today’s networked information economy. The success of the J2EE platform is in large part due to the success of this model.
Today, all leading application server and enterprise information system vendors have adopted the J2EE standard and introduced products based on the J2EE platform specification. Application architects and developers have come to rely on the J2EE standard to help them solve the various design challenges that face them day to day.
While the fundamentals of the J2EE platform are relatively easy to describe, mapping these features to architectural issues in the design of distributed applications requires deeper understanding and careful decision making. Although the J2EE standard offers a simplified programming model compared to previous alternatives, the platform isn’t monolithic. Certain features require that architects and developers weigh their options before making design decisions and be prepared to re-think those decisions as they uncover new challenges. That, in turn, requires some understanding of the design motivations behind the platform and of the trade-offs involved in applying specific design features to a specific architectural problem. |

| | Chebyshev PolynomialsChebyshev polynomials crop up in virtually every area of numerical analysis, and they hold particular importance in recent advances in subjects such as orthogonal polynomials, polynomial approximation, numerical integration, and spectral methods. Yet no book dedicated to Chebyshev polynomials has been published since 1990, and even that work... | | The School of Doubt (Brill Studies in Skepticism)
The School of Doubt conducts a parallel philological and philosophical examination
of Cicero’s Academica, a work on Hellenistic epistemology written in
the first half of 45 bce. The treatise has a unique history, insofar as fragments
of two different versions are extant: the second of a two-volume first edition,
a dialogue... |
