About EclipseLink JPA

This section introduces EclipseLink implementation of Java Persistence API.

As a specification, JPA needs to be implemented by vendors or open source projects.

EclipseLink provides a complete, EJB 3.0-compliant JPA implementation. It provides complete compliance for all of the mandatory features, many of the optional features, and some additional features. The additional nonmandatory functionality includes the following:

  • object-level cache;
  • distributed cache coordination;
  • extensive performance tuning options;
  • enhanced Oracle Database support;
  • advanced mappings;
  • optimistic and pessimistic locking options;
  • extended annotations and query hints.

EclipseLink offers support for deployment within an EJB 3.0 container. This includes Web containers and other non-EJB 3.0 Java EE containers. For more information, see Deploying an EclipseLink JPA Application.

Through its pluggable persistence capabilities EclipseLink can function as the persistence provider in a compliant EJB 3.0 container.

For more information, see About EclipseLink.
