JPA 2.0 Preview Limitations

With the JPA 2.0 there are some capabilities that are incomplete or differ in functionality from the current draft specification

  • In EclipseLink 1.2.0 there exists javax.persistence.criteria.QueryBuilder which has been renamed to javax.persistence.criteria.CriteriaBuilder in the final draft of the JPA 2.0 specification
  • Metamodel: Some API not yet implemented or partially functional
    • IdentifiableTypeImpl.java
    • MappedSuperclassTypeImpl.java - Partially implemented: public Type<?> getIdType()
    • EntityTypeImpl.java - Partially Implemented: public Type<?> getIdType()


The following features have been newly deprecated in the 2.0 release

Component Feature Description
JPA Standard Properties JPA 2.0 introduces common properties for JDBC configuration. The implementation of these makes some of the existing 'eclipselink.jdbc.*' properties redundant for both JPA 1.0 and 2.0 usage and therefore have been deprecated in this release. They will be removed in a future release. In Eclipselink 1.2.0 the use of these properties will result in a log warning.
