Enterprise JavaBeans, Second Edition

Organization

Here’s how the book is structured. The first three chapters are largely background material, placing Enterprise JavaBeans in the context of related technologies, and explaining at the most abstract level how the EJB technology works and what makes up an enterprise bean. Chapter 4 through Chapter 7 goes into detail about developing enterprise beans of various types. Chapter 8 and Chapter 9 could be considered “advanced topics,” except that transactions (Chapter 8) are essential to everything that happens in enterprise computing, and design strategies (Chapter 9) help you deal with a number of real-world issues that influence bean design. Chapter 10 describes in detail the XML deployment descriptors used in EJB 1.1. Finally, Chapter 11 is an overview of the Java™ 2, Enterprise Edition ( J2EE) with regard to EJB 1.1.

Chapter 1

This chapter defines component transaction monitors and explains how they form the underlying technology of the Enterprise JavaBeans component model.

Chapter 2

This chapter defines the architecture of the Enterprise JavaBeans component model and examines the difference between the two basic types of enterprise beans: entity beans and session beans.

This chapter explains how the EJB-compliant server manages an enterprise bean at runtime.

Chapter 4

This chapter walks the reader through the development of some simple enterprise beans.

Chapter 5

This chapter explains in detail how enterprise beans are accessed and used by a remote client application.

Chapter 6

This chapter provides an in-depth explanation of how to develop container-managed and bean-managed entity beans and describes their runtime behavior.

Chapter 7
