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
- Develop model for testing access type settings
- approx 2 days
- 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()

Open Issues
- Deprecation of existing properties
- Backwards compatibility?
- Forward Migration?
- When should we finally remove the eclipselink.* properties?
