Description Gordon Yorke CLA 2008-09-24 15:36:20 EDT 
JPA 2.0 added additional EntityManager APIs.  New API was added which allow 'lock modes' to be applied to methods find and refresh.  API was added to allow access to an objects current lock status.  API was added to allow removal of an Entity from the persistence context ( clear(Object entity) ).  Additional miscelanious API was added.

See http://wiki.eclipse.org/index.php?title=EclipseLink/Development/JPA_2.0/entitymanager_updates for details

Comment 4 Gordon Yorke CLA 2009-01-28 15:57:33 EST 
Not all of the reported properties are supported at the EM level.  Only:
JOIN_EXISTING_TRANSACTION
PERSISTENCE_CONTEXT_REFERENCE_MODE
PERSISTENCE_CONTEXT_CLOSE_ON_COMMIT
PERSISTENCE_CONTEXT_PERSIST_ON_COMMIT
PERSISTENCE_CONTEXT_FLUSH_MODE
ORACLE_PROXY_TYPE
EXCLUSIVE_CONNECTION_MODE
EXCLUSIVE_CONNECTION_IS_LAZY
CONNECTION_POLICY
VALIDATE_EXISTENCE
FLUSH_CLEAR_CACHE

Quite a few revisions have occurred with substantial changes to the format of files since the patched revisions.  Care should be taken when resolving conflicts and checking in the patch.

Otherwise looks ready for check-in.
Comment 5 Gordon Yorke CLA 2009-01-28 16:11:12 EST 
Ignore my comment on the supported properties list.  The properties as specified within the patch is correct.
Comment 6 Mitesh Meswani CLA 2009-01-30 17:10:06 EST 
Checked in all of JPA 2.0 EntityManager API updates (except those required by Criteria Query) on behalf of Darani. 

The changes are at http://fisheye2.atlassian.com/changelog/eclipselink/?cs=3362

Leaving this issue open for the Criteria Query work.
Comment 7 Darani Yallapragada CLA 2009-03-10 16:46:08 EDT 
I updated the wiki with the latest methods to be implemented in EM API. I am working on implementing those methods.

Comment 10 Darani Yallapragada CLA 2009-03-24 20:10:40 EDT 
CascadeType.Detach is yet to be completed
Comment 11 Mitesh Meswani CLA 2009-03-25 22:47:23 EDT 
Checked in a patch on behalf of Darani. http://fisheye2.atlassian.com/changelog/eclipselink/?cs=3779
Please note that the implementation of detatch() needs to updated to take into account CascadeType.DETACH
Comment 12 Gordon Yorke CLA 2009-04-01 11:35:13 EDT 
This bug was intended to cover the new Query APIs like getSupportedHints() and getHints().

The Wiki pages should be the guides on what should be implemented.

*** Bug 270196 has been marked as a duplicate of this bug. ***
Comment 14 Gordon Yorke CLA 2009-04-01 15:44:49 EDT 
Additionally an open issue with em.detach() is that triggered indirection on a detached instance for mappings marked as CascadeType.DETACH must return detached instances as well.  Currently those instances would be managed as would be expected for non CascadeType.DETACH mappings.
Comment 15 Doug Clarke CLA 2009-04-08 15:09:39 EDT 
Changing priority to P@ since JPA 2.0 features are required for the 2.0 release
Comment 16 Gordon Yorke CLA 2009-10-30 13:43:03 EDT 
Initial development completed
Comment 17 Eclipse Webmaster CLA 2022-06-09 10:04:50 EDT
