Chapter 24. Examples for Chapter 11

In Chapter 11, you learned a bit about how JAX-RS fits in the grander scheme of things like Java EE and Spring. In this chapter, there are two similar examples that define the services illustrated in Chapter 2. The first marries JAX-RS with EJB. The second uses the Spring form to write our JAX-RS services. Instead of using in-memory maps like the earlier examples in the workbook, both examples use Java Persistence (JPA) to map Java objects to a relational database.
