Java Server Programming:Principles and TechnologiesBy Subrahmanyam Allamaraju, Ph.D.SummaryBuilding and managing server-side enterprise applications has always been achallenge. Over the last two decades, the role and importance of server-sideapplications has increased. The twenty-first century economy dictates that ecommerceand other enterprise applications are transparent, networked, adaptable, andservice-oriented. These demands have significantly altered the nature of applications.As enterprises migrate from closed and isolated applications to more transparent,networked, and service-oriented applications to enable electronic businesstransactions, server-side technologies occupy a more prominent place. Despite thedisparity of applications that exist in any enterprise, server-side applications are whatpower twenty-first century enterprises!The purpose of this article is two-fold. Firstly, this article attempts to highlight thetechnical needs for server-side applications, and thereby establish a set ofprogramming models. Secondly, based on these programming models, this articleintroduces the reader to the Java 2, Enterprise Edition (J2EE).If you are a beginner to server-side programming, or the J2EE, this article willhelp you gain an overall perspective of what this technology is about. If you arefamiliar with one or more J2EE technologies, this article will provide the basicprinciples behind server-side programming, and help you relate these principles tospecific J2EE technologies.IntroductionBuilding and managing server-side enterprise applications1 has always been achallenge.
