Java Persistence API (JPA) is an object-relational mapping (ORM) framework, that is, it maps objects to relational databases. JPA provides the standard for object-relational mapping in the Java language. JPA can use either Standard or Enterprise Edition Java.
EclipseLink is one implementation of JPA. It is an open source project, and it works with a large number of databases or platforms. Pervasive has added PSQL as an EclipseLink JPA platform.
The Pervasive database Platform file has been submitted to EclipseLink and is awaiting full promotion. For the latest information about its status and download, go to http://www.pervasivedb.com and navigate to the SDK section of the website.
Using JPA requires the JPA package itself (see Getting Started for download link), a Java installation, and an installation of PSQL v11 SP3.
To access the runtime files for the EclipseLink JPA access method, go to the EclipseLink website: http://www.eclipse.org/eclipselink.
The latest information about the status of PSQL JPA is available in the SDK section of the Pervasive database website: http://www.pervasive.com/database. The latest Pervasive release of PSQL JPA is also available at this site.
Deployment of PSQL JPA requires configuration of the persistence.xml life. Download of PSQL JPA includes a sample persistence.xml file. The sample file includes a persistence unit, demo, a class, JPADemo, and a database, simpleDB on localhost. Modify these values as appropriate.
The PSQL EclipseLink JPA platform implementation has certain limitations:
