Introduction xxi Chapter 17 covers integration to and from EJB platform in-depth. It provides introduction to the various styles of integration, followed by a discussion of various techniques for integrating EJB with the outside world. It explains the J2EE Connector Architecture, a predominant framework for integrating EJB with back-end enterprise applications, and discusses a connector example. Chapter 18 covers EJB tips and techniques for designing and deploying EJB for better performance. You ll learn about design strategies that will help you make decisions such as when to choose between stateful versus stateless session beans, when to choose between local and remote interfaces, and so on. The chapter also focuses a great deal on providing performance tuning tips for different types of beans. Chapter 19 discusses clustering in large-scale EJB systems. You ll learn about how clustering works behind the scenes and learn a few strategies for how containers might achieve clustering. This is a critical topic for anyone building a system that involves several machines working together. Chapter 20 covers EJB project management. We ll talk about how to get your project started on the right foot. This includes guidelines on choosing between J2EE and .NET frameworks for your projects, building a first pass of your system, dividing your development team, and many such concepts. Chapter 21 provides guidelines for choosing the right EJB server for your needs. We ll describe our methodology for how an organization can compare and contrast different vendors offerings. We ll also list our set of criteria for what we would want in an EJB server. Chapter 22 shows how to build a real-world J2EE system using EJB components. We ll see how the EJB components should be used together in an enterprise, as well as how to connect them with clients using Java servlets and JavaServer Pages (JSP) technology. We ll also demonstrate how to design an EJB object model using UML. The Appendixes are a collection of ancillary EJB topics. Some developers may want to read the appendices, while some may not need to do so. Appendix A teaches you Java Remote Method Invocation over the Internet Inter-ORB Protocol (RMI-IIOP) and the Java Naming and Directory Interface (JNDI). These technologies are prerequisites for using EJB. If you re just starting down the EJB road, you must read this appendix first. Appendix B discusses how to integrate EJB and CORBA systems. We ll learn about how EJB and CORBA are interoperable through
