Eclipselink jpa.png This page lists all sections in the EclipseLink User's Guide for JPA (Java Persistence API) projects. You can also use EclipseLink's Native ORM support to extend JPA.


Developing Applications using EclipseLink JPA

Step 1

Define your persistence units in persistence.xml.

Step 2

Annotate classes with @Entity, @Embeddable, and @MappedSuperClass and/or define classes in your mapping file (orm.xml).

Step 3

Configure your application with:

  • javax.persistence.transactionType
  • javax.persistence.jtaDataSource
  • javax.persistence.nonJtaDataSource
