Concurrent threads can operate on an OpenJPA EntityManager. However, by default, EntityManager is not thread-safe. Try <property name="openjpa.Multithreaded" value="true"/>
Please note that this flag will ensure that OpenJPA will protect all its internal data structures for concurrent access. But the persistent entities being operated upon are in user control. The user application has to ensure their thread-safety. ----- Pinaki Poddar Chair, Apache OpenJPA Project -- View this message in context: http://openjpa.208410.n2.nabble.com/Multithreading-problem-tp6839678p6840293.html Sent from the OpenJPA Users mailing list archive at Nabble.com.
