Using the Java Persistence API in Desktop Applications

Overview

The JSR 220 specification defines Enterprise JavaBeans 3.0. One of its primary goals is to simplify the creation, management, and storage of entity beans. Working towards that goal, Sun Microsystems and supporting community developers created a new Application Programming Interface (API) that lets one use "Plain old Java objects" or POJOs as the persistable entities. The Java Persistence API facilitates the use of POJOs as entity beans and significantly reduces the need for complicated deployment descriptors and extra helper beans. Additionally, one can even use the API in desktop applications.
