Hi All
I have a scenario and am trying to evaluate the performance of using the entity
manager in a Message Driven Bean (MDB)
class MDBean {
@persistencecontext(....)
private EntityManager em;
public void onMessage() {
....
while (someCondition) {
ClassB b = new ClassB();
b.setEntityManager(em);
b.doSomething();
}
............
}
Basically ClassB carries out persisting of about 6 tables based on the
entitymanager passed to it. This process happens in a loop and the loop runs
for about 10 - 20 times. I was wondering if I need to close the entity maanger
at some point and re-create it? What would be the performance hit if any? Let
me know what other design considerations need to be taken into account?
Thanks
K
