1、外文原文 PART ONE Overview In Part I, we introduce the server-side development platform that is the Java 2 Platform, Enterprise Edition (J2EE), of which the Enterprise JavaBeans (EJB) component architecture is a vital piece. J2EE is a conglomeration of concepts, programming standards, and innovationsall

2、 written in the Java programming language. With J2EE, you can rapidly construct distributed, scalable, reliable, and portable secure server-side deployments. Chapter 1 begins by exploring the need for a server-side development platform such as J2EE. Youll see the rich needs of server-side computing,

3、 such as scalability, high availability, resource management, and security. Youll also see the need for a rapid application development component architecture such as EJB and COM+. Well wrap up by surveying Sun Microsystems J2EE, a complete server-side development platform. Chapter 2 moves on to the

4、 Enterprise JavaBeans component model. Well take a look at how EJB empowers heterogeneous vendors to collaborate to solve a business problem, and well study the roles of each party in an EJB deployment. Well also look at the different functional software modules in an EJB deployment and how they rel

5、ate. Server-side Component Architectures Enterprise JavaBeans (EJB) is a server-side component architecture that enables and simplifies the process of building enterprise-class distributed object applications in Java. By using EJB, you can write scalable, reliable, and secure applications without wr

6、iting your own complex distributed object framework. EJB is about rapid application development for the server side; you can quickly and easily construct server-side components in Java by leveraging a prewritten distributed infrastructure provided by the industry. EJB is designed to support application portability and reusability across any vendors enterprise middleware services. If you are new to enterprise computing, these concepts will be made very clear shortly. EJB is a complicat
