Typically, in order to perform user tasks or process requests from client applications, the business methods in the session bean require one or more types of resources. These resources can be other session beans, data sources, or message queues. The resources that the stateless session bean is trying to use can be injected using annotations or deployment descriptors. Resources can be acquired by annotation of instance variables or annotation of the setter methods. Listing 2-5 shows an example of setter and instance variable–based injection of myDb, which represents the data source.

In the “How This Book Is Organized” section, we provided a summary of each chapter to illustrate the general flow of the chapters, and to help you decide which areas to focus on first, should you wish to read the chapters out of sequence. The chapter concluded with a “Getting Started” section to help you install and configure the GlassFish Java EE reference implementation, set up required environment properties, and verify that the installation was successful. With this, you now have the required software infrastructure to run the code samples in this book and examine the many features of EJB 3 over the following chapters.

EJB was born to fill this need. Over the past 10 years, it has evolved to encompass numerous features (while ejecting others) and has matured into a robust and standard framework for deploying and executing business components in a distributed, multiuser environment. What Is EJB? EJB 3 is defined by JSR 220: Enterprise JavaBeans 3. Whereas the previous versions of EJB were captured in a single document, this JSR now spans three documents (listed following). The first document provides a synthesis of the high-level features of the new release, and focuses on the new simplified development model for building EJB components.
