[JBoss-user] [JBoss Eclipse IDE (users)] - Re: EJB3 @Column(primaryKey = true) problem
Try this: @Id @Column(name = xxx, nullable = false, updateable = false, insertable = false) The @Id annotation type is to indicate that the column/field is a primary key.

[JBoss-user] [EJB 3.0] - EJB3 Entity Primary Key Retrieval
Hi, I have a problem with retrieving the primary key of an entity object after persisting. My case is: :- I have an entity object which has the id as the primary key field of type long and the value is auto generated by the database (and with all necessary annotations assigned) :- After I invoke the EntityManager em to persist my entity (e.g. em.persist(entityObj) ), I want to know what was the newly assigned primary key by the database. So, is there any way to retrieve the newly assigned primary key of the entity, since the EntityManager.persist() method returns nothing (void)? Any suggestion will be greatly appreciated. Thank you.

[JBoss-user] [EJB 3.0] - EJB3 Session Bean (Bean Managed Transaction) issue
Hi,
I have a problem with getting bean managed transaction or more appropriately
user managed transaction to work on my Session Bean (EJB3 specs.)
I have a session bean with the EntityManager em already defined and I have a
method xxx() which is suppose to rollback all which persistence when one of
them failed.
I tried to obtain the EntityTransaction by calling:
EntityTransaction trxn = em.getTransaction();
try
{
trxn.begin();
//do something...
trxn.commit();
}
catch(Exception ex)
{
trxn.rollback();
}
Unfortunately, JBoss throws IllegalStateException while calling
em.getTransaction(). May I know how do I configure the session bean to be able
to handle user managed transaction instead of container managed transaction
(like the old days where we could define that in the ejb-jar.xml)? I'm running
on JBoss 4.0.4RC1.
Any help will be greatly appreciated. Thank you.
