Chapter 1. Enterprise JavaBeans™ in context
Overview
This introductory chapter describes the goals and requirements of EJB technology and what you—the developer—can expect to gain by using it. It explains how EJBs fit into other distributed programming paradigms (like CORBA), and into the wider ‘J2EE’ model of application development. The chapter includes an outline of the other services that a J2EE-compliant application server is expected to provide and which EJBs can use (e.g., JavaMail, JMS). There is a brief discussion of the development philosophy that underlies the EJB Specification, including the roles of the developer, assembler, and deployer, and how the EJB model—appropriately used—can enhance code reuse and improve reliability.
