I am trying to use a Stateless Session Bean and Container Managed Persistence to update data in my data base using aWeblogic 10 server, Oracle 10 database and the supplied Kodo PersistenceManager. My persistence xml looks like this:
<persistence-unit name="myManager" transaction-type="JTA">
<jta-data-source>MyDataSource<jta-data-source>
<class>MyClass</class>
</persistence-unit>
I can find the data just fine. When I modify a value and call persist that seems to execute without and error, at least none that I have been able to detect. However when I look at the database the data has not been modified.
If I simply create the EntityManager and call em.getTransaction().begin(), modifiy the data, call persist, then call em.getTRansaction().commit() the data in the DB has been modified. However this way I am not letting the container manager the transaction.
Any suggestions as to what I am doing incorrectly or how to get more information.
thanks in advance
