Transaction Management in multiple Entities in one transaction
--------------------------------------------------------------
Key: OPENJPA-2155
URL: https://issues.apache.org/jira/browse/OPENJPA-2155
Project: OpenJPA
Issue Type: Question
Components: jpa
Affects Versions: 2.1.1
Environment: WebSphere Application Server 6.1.37 on Windows and AIX
Reporter: Prabhat
I am a new user on OpenJPA,
I have a scenario where I need to perform update/insert in multiple entities on
one transaction. How to achieve this?
example of EntityManager update method (auto generated by Rational Software
Architect8.0.3). [ The same way, I have two more entities. ]
==================
@Action(Action.ACTION_TYPE.UPDATE)
public String updateKna1(Kna1 kna1) throws Exception {
EntityManager em = getEntityManager();
try {
em.getTransaction().begin();
kna1 = em.merge(kna1);
em.getTransaction().commit();
} catch (Exception ex) {
try {
if (em.getTransaction().isActive()) {
em.getTransaction().rollback();
}
} catch (Exception e) {
ex.printStackTrace();
throw e;
}
throw ex;
} finally {
////em.close();
}
return "";
}
==========================
If I keep commit/rollback in each entity then I can not rollback from all
previous entities (if last entity insert or update fails).
Can you help me on this?
Thanks in Advance.
