I am using openjpa1.0. My main entity class is RecPolicy which has a
@OneToMany relation to entity 'CallLog'. I am using 'LAZY' fetch and
'ALL' for cascade. See corresponding field below:
Public class RecPolicy {
...
@OneToMany (fetch=FetchType.LAZY, cascade=CascadeType.ALL)
private List <CallLog> calls;
}
Now I am trying to add a CallLog entry to an existing RecPolicy entry,
but it's not working. My code looks like
EntityManager em =
factory.createEntityManager();
EntityTransaction tx = em.getTransaction();
try {
tx.begin();
RecPolicy.RecPolicyId policyId = ...
RecPolicy policy =
em.find(RecPolicy.class, policyId);
CallLog callLog = new CallLog(sid,
this.fromUri, this.toUri);
policy.calls.add(callLog);
tx.commit();
} catch (Exception e) {
if (tx.isActive()) tx.rollback();
} finally {
em.close();
}
When I enable openjpa logging all I see is an UPDATE sql to update the
RecPolicy, but no INSERT for CallLog? Do I need to persist new CallLog
above explicitly? Is 'LAZY' fetch causing this behavior?
