EclipseLink JPA

Database and Application Server Support

EclipseLink supports a number of database platforms and application servers, as described below.

Database Support

EclipseLink supports any relational database that is compliant with SQL and has a compliant JDBC driver. EclipseLink has extended support for several database platforms. The extended support mainly consists of providing native sequencing support, schema creation, and certain database functions.

The following databases are supported. Click the names below to see the Javadoc that describes the support for that platform. The classes are in the org.eclipse.persistence.platform.database package.

It also possible to extend EclipseLink to add extended support for additional platforms. There are also several user contributed platforms in the EclipseLink incubator project. See Platform Incubator.

Application Server Support

EclipseLink can be used with any Java EE application server that meets the software requirements through the EclipseLink API.

EclipseLink provides integration support for the following servers. See the Javadoc for more information. These classes are concrete subclasses of org.eclipse.persistence.platform.server.ServerPlatformBase responsible for representing server-specific behavior. These classes provide the behavior for the following:

  • Which external transaction controller to use
  • Whether or not to enable JTA (external transaction control)
  • How to register/unregister for runtime services (JMX/MBean)
  • Whether or not to enable runtime services
  • How to launch container Threads
