How to get EntityManager in callback methods (Pre/Post Remove, Update, Persist)

[Miroslav Nachev]

Hi,

In callback methods (PreRemove, PreUpdate, PrePersist, PostRemove,
PostUpdate, PostPersist) of an Entity Bean I need to execute native SQL
statement in the same transaction. How to retrieve current EntityManager
from which to get Connection object?
Are there any helper tools in OpenJPA for that purpose?


Regards,
Miro.
