Is it possible to reuse instances from transaction to transaction?
I would like to be able to create a bean in one transaction, detach
it and reattach the same instance in a new transaction. My goal here
is specifically to reuse instances across transactions because they
have a very expensive creation cost, and no I can not redesign the
system.
I tried a quick test case using merge, but merge returned a new
instance:
beginTx();
Employee dain = entityManager.find(Employee.class, dainPk);
assertEquals(dain.getFirstName(), "Dain");
commitTx();
beginTx();
assertSame(dain, entityManager.merge(dain));
assertEquals(david.getFirstName(), "Dain");
commitTx();
When I try to use the refresh method, OpenJPA complains that the
entity "is not managed by this context".
So is there anyway for me to reuse instances?
-dain
