This document discusses using JAX-RS and JPA to build RESTful web services. It provides an overview of REST principles and JAX-RS, and shows how the HTTP methods map to CRUD operations in JPA. Some challenges in mapping JPA entities to XML are also outlined, such as bidirectional relationships and composite keys.

Editor's Notes
- Java Applications need to either access existing data sources like relational database or interact with other systems via XML—or BOTH. The example is a trivial one but it can get very complicated to map between an Java object model and a relational or XML schema.
