Chapter 26

Persistence in the EJB Tier

This chapter describes how to use the Java Persistence API from enterprise beans. The material here focuses on the source code and settings of two examples. The first example called order is an application that uses a stateful session bean to manage entities related to an ordering system. The second example is roster, an application that manages a community sports system. This chapter assumes that you are familiar with the concepts detailed in Chapter 24, Introduction to the Java Persistence API.
