This reference contains the API documentation (similar to JavaDoc) of the Java Persistence API (JPA) 2.0. The content is derived from the original JPA documentation (in the EclipseLink JPA 2 RI) with some additions and notes. The JPA types are organized into the following sections: The purpose

A named query is a statically defined query with a predefined unchangeable query string. Using named queries instead of dynamic queries may improve code organization by separating the JPQL query strings from the Java code. It also enforces the use of query  parameters

The JPA Metamodel API, which is introduced in JPA 2.0, enables examining the classes, fields and properties of the persistent object model, similarly to the Java reflection API. The main interface of the JPA Metamodel API is: Types (mainly classes) and attributes (persistent field and properties

This chapter explains how to manage ObjectDB databases using the Java Persistence API (JPA). The first two pages introduce basic JPA interfaces and concepts: The next section explains how to use JPA for database CRUD operations: More advanced topics (e.g. locking and events) are discussed in the last section:

Working with the Java Persistence API (JPA) consists of using the following interfaces: Overview A connection to a database is represented by an EntityManager instance, which also provides functionality for performing operations on a database. Many applications require multiple database
