JPA 2.0: Standardized Properties

JPA 2.0 Root | bug 249023

Date Committer(s) Description
Feb 2, 2009 dclarke Initial feature template

Summary

In JPA 2.0 the specification has defined standard persistence unit properties for JDBC setting. These properties will need to be supported

See JPA 2.0 ED section 7.2.1.7 (previously 6.2.1.7) for details.

  • Java EE and SE Properties
    • javax.persistence.query.timeout — value in seconds for query timeout
  • Java SE Properties
    • javax.persistence.jdbc.driver — fully qualified name of the driver class
    • javax.persistence.jdbc.url — driver-specific URL
    • javax.persistence.jdbc.user — username used by database connection
    • javax.persistence.jdbc.password — password for database connection validation

Work Estimate

  1. Develop model for testing access type settings
    approx 2 days
  2. Update processing
    approx 2 days

Functional Requirements

  • Support using new standard property names
  • Support using existing eclipselink.jdbc properties as completely interchangeable with standard ones
  • Implement EntityManagerFactory.getSupportedProperties() and EntityManager.getSupportedProperties()

Design

Documentation

Testing

Open Issues

  1. Deprecation of existing properties
    • Backwards compatibility?
    • Forward Migration?
    • When should we finally remove the eclipselink.* properties?
