Hi Mauro,
No. joinTransAction() should be called after all transactions but before
closing the Entity Manager. This has the effect of committing all queued
transactions to the DB at once (even if there is only one).
It might be easier to use CMP with annotations like I did in the example.
This has the effect of not having to rollback transactions in case of
exceptions since it will be done automagically.
You will have to use
@TransactionAttribute(TransactionAttributeType.REQUIRED)
however to trigger the automatic rollback feature.
I remember a very good article about all this but I can't seem to find it
anymore. Let me see if I can dig it up from my bookmarks.
In the meantime let me know if it helps pls.
Wim

Hi Wim,
thank you for your help. I've changed my code in this manner:
<code>
EntityManager entityManager =
javax.persistence.Persistence.createEntityManagerFactory("MyRentStorePU").cr
eateEntityManager();
try {
entityManager.joinTransaction(); // New line
entityManager.getTransaction().begin();
entityManager.persist(cliente);
entityManager.getTransaction().commit();
</code>
Is it correct?
I obtain the same exception :-(
In a previous email you suggest to change persistence.xml using JTA
instead JPA. I've noticed that I'm just using JTA. I post my
persistence.xml:
<?xml version="1.0" encoding="UTF-8"?>
<persistence version="1.0"
xmlns="
http://java.sun.com/xml/ns/persistence"
xmlns:xsi="
http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="
http://java.sun.com/xml/ns/persistence
http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd">
<persistence-unit name="MyRentStorePU" transaction-type="JTA">
<jta-data-source>jdbc/myrentstore</jta-data-source>
<class>it.myrent.store.entity.Clienti</class>
<class>it.myrent.store.entity.CreditCard</class>
<class>it.myrent.store.entity.Ordini</class>
<exclude-unlisted-classes>true</exclude-unlisted-classes>
<properties>
<property name="toplink.ddl-generation" value="create-tables"/>
<property name="toplink.logging.level" value="FINE"/>
</properties>
</persistence-unit>
</persistence>
What should I do?
Thanks in advance,
Mauro Chiarugi
