Hi to all,
I'm having some troubles using OpenJPA in a multithreaded environment.
Sometimes (because it happens randomly) some entities aren't
persisted, but
OpenJPA doesn't throw any exception. Please note that I persist a
set of
entities (instances of the same class) that don't share any kind of
information.
I haven't set the property openjpa.Multithreaded to true because I
use a
different EntityManager for each thread (I get it through a
ThreadLocal).
Obviously If I set this property everything seems to work right.
So I want to understand why I have to set this property: I'm not doing
something right or property openjpa.Multithreaded is mandatory for
multithreaded environments (even using different EntityManagers) ??
Did you compared using == what you think is different instance of
EntityManager ?
Reading your message tend to prove that EntityManager is shared and
when you think you got a new one it is not a new one.
Thank you for the help,
Claudio
