Type-Safe Criteria and MetaData API in JPA 2.0 - Expert Group Delivers Proposed Final Draft

ALT DESCR

One more JavaEE 6 specification in Proposed Final Draft: Linda has announced the availability of JPA 2.0 PFD. This draft includes a number of significant changes, including the replacement of an earlier version of criteria API with a typesafe API, support for validation, and a metamodel API.

As pointed by Linda, the changes to the criteria API and the new metamodel API came through a proposal from Gavin to the EG; a great example of how the EG can pool the expertise from experts in the Java community, regardless of their company affiliation.

Download the PFD spec from the JSR 317 site and give feedback to the EG on this one... and the others that will follow as JavaOne is playing its usual role of forcing function.
