I try to limit unnecesery joins in my queries, because in the case of
pessimistic locking this behavoiur locks too much.
By the way previously I was using h
Try changing your PersistenceContext injection attribute from "name" to
"unitName" to refer to your persistence unit.

Without at minimum a snippet of code it's pretty hard to help you out.

my problem.

Nothing else is jumping out at me so I'm cross-posting to us...@openejb. I'm
not sure what PersistenceUnit 'null' means in this context - they might be
able to shed some light on the message though.

Hi Rick,
Sorry, I am afraid I cannot. Would you please let men know what bug on
detachCopy method?
And one more question, if I get em from jpaTample, and from em find data, do
I need always close em after?
Thanks,

Hi,
Let's say I have the following persistence class:
@Entity
public class B {
@OneToOne(cascade = CascadeType.PERSIST, fetch = FetchType.LAZY)
@JoinColumn(name = "a_id")
private A a;
}
and when I try to execute this JPA query:
SELECT b.a.id FROM B where B.id = 123
my SQL output looks li
I tried changing version=2.0, and using detach on em, but the entity still
did detached. :(

version="2.0">
This is the only place to change the version, where am I still miss
Hello Mike,
It's in the META-INF directory of the ejb.jar that I deploy.
We are deploying to a Geronimo AS (2.1.4) that uses openejb-3.0.1. Might this
have been a bug in
that version that has been solved since then.

Try changing version="1.0" to version="2.0" and removing don't use the
detachCopy method. I think that this is a bug that I reported [1] a while
back.
Thanks,

Thanks Rick for your responding, do you mean there is any configuration in
persistence.xml?
My file is very simple:
http://java.sun.com/xml/ns/persistence";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
version="1.0">
org.apache.openjpa.persistence
Can you post your persistence.xml file?
Thanks,
Rick
Hi,
Where is the persistence.xml file in your ejb.jar? It should be in the
META-INF directory.
The container will look for persistence.xml files in the following places
(per JPA spec):
In Java EE environments, the root of a persistence unit must be one of the
following:
• an EJB-JAR file
• the WE
Hi Rick,
I solved this problem by casting the EntityManger to OpenJPAEntityManager
and using detachCpoy method which it return detached entity. Properly detach
method is a bug need fix.
