In other words, instead of saying this
SELECT b.a.id FROM B where B.id = 123
You should have
SELECT b.a_id FROM B where B.id = 123

I guess what I am saying is that this join is necessary. In standard SQL the
only way you are going to get relational data from two tables is by joining the
tables or performing nested selects. I think the thing you want to do is to
just look for the column on table "B" that corresponds to th

I have never tried to use JPA with Stored Procedures so excuse my ignorance.
If it is difficult or not available, it would benefit the spec if JPA would
easily use stored procedures and views just like it uses tables. The only
thing I think would need to be added to a marked-up Entity Object i

Have you tried using a different MySQL driver? I ran into general database
issues when trying to use MySQL 4.X with the latest greatest MySQL Driver. I
now use MySQL connector 3.0.17 and have not had database issues and that
includes working with OpenJPA 1.2.1

Based on the code that has been provided I am making the assumption that you
are mapping your OneToMany to a Set collection. If this is the case, a Set
collection will not allow duplicates. In order to check for duplicates, an
object that is getting placed in the Set needs to show how it is un
It looks like you are trying to add items to a Set. You will get these casting
exceptions if your classes do not implement the IComparable interface. If they
do implement the interface, then it is another issue.

Just a quick question. Is the table already created or are you trying to use
OpenJPA to create the table?

This is an open-ended question for everyone on the panel. What is your
thoughts on the EAO pattern in a JEE environment? Is it useful? Is it just
too much overhead? I am trying to really analyze if this is a viable solution

changing this to
openjpa.jdbc.SynchronizeMappings=validate. This still did not work as it was
still trying to synchronize schema. I then went into the persistence.xml and
explicitly added the property . From then on, everything worked the way it should.

I am having a problem that I believe is associated with the JPA module. I have
created some entity objects and EJB's. When I run through the continuous build
process, it deploys the objects to Geronimo (where OpenJPA is the persistence
layer). The first time I try to access the object, the v

I am using the openjpa within the Geronimo container. Is there a way that I
can tell Geronimo to do this or is this a question for the Geronimo group?
