JSR 317 - Java Persistence 2.0
Abstract
One of the key outcomes of Java EE 5 / EJB 3.0 was the introduction of the Java Persistence API-- a new, standard API for Java persistence and object/relational mapping that supports use in both Java EE and Java SE environments.
The purpose of Java Persistence 2.0 is to augment the Java Persistence API to include further features requested by the community.
This session will give you an up-to-the-minute glimpse into work in progress on Java Persistence 2.0, and will provide you with an opportunity for feedback on new directions.
Aspects to be discussed include the following:
- Expanded modeling capabilities and object/relational mapping functionality, including support for collections of embedded objects, ordered lists, combinations of access types, greater flexibility in combining existing mapping options, etc.
- Expanded query capabilities and additions to the Java Persistence query language
- Standardiztion of additional contracts for entity detachment and merge, and persistence context management
- Standardization of sets of "hints" for entity manager and query configuation
- Expanded pluggability contracts for Java EE environments
