Hi,
In my application I have several EntityManager at the same time. In some cases I delete entities via a native query (to increase the performance) - NOT via EntityManager.remove(..). My question is: How to remove these (already deleted) entities from all/one EntityManager?
Re-initialization oft he existing EntityManager is not a accepted solution.

Note: I have a List with all removed entities - So I have all necessary information about the deleted entities.

Thanks
QStorm

Seems like there is no JPA-1.0-compliant way to do this.

The only way I can think of is to access the hibernate -Session (which is the EntityManager's delegate) and use session.evict(anObject)...

Hi,
Thanks for the answer. It seems to work. Here the code for someone with the same issue:

Code:
final List<Entity> entities = new ArrayList<Entity>();
// ...
final SessionImpl session = (SessionImpl) manager.getDelegate();
for(E current : entities) session.evict(current);


Best regards
QStorm
