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

  • Criteria API
    • QueryBuilder (javax.persistence.criteria) has been renamed to CriteriaBuilder in the final JPA 2.0 release
    • Predicate.negate will be renamed to Predicate.not in final JPA 2.0 release
    • Majority of QueryBuilder operators not yet implemented
  • Metamodel: Some API not yet implemented or partially functional
    • IdentifiableTypeImpl.java: get*Id and get*Version methods
    • MappedSuperclassTypeImpl.java - Partially implemented: public Type<?> getIdType()
    • EntityTypeImpl.java - Partially Implemented: public Type<?> getIdType()


Dynamic Weaving on JBoss Server

Using EclipseLink with JPA Dynamic Weaving on JBoss 5.1.0 (and higher) may result in multiple exceptions. This issue occurs only with dynamic weaving -- static weaving executes correctly. For information on using static weaving, see Static Weaving/EAR Packaging Modifications in the EclipseLink documentation.

See Bug 293581 for details on this issue.

Deprecation

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.
