OpenJPA is used for many purposes. It will not be fair to reduce its
applicability as narrowly as you suggest.
But if an application is not challenged by object-relational mapping, ACID
transaction integrity
I have seen this. Had no definite closure.
Seemingly occurs with certain version of Ant, JDK, Maven etc...
The error stopped me for several days -- and disappeared as mysteriously as
it appeared when I tweaked with different version of Ant.

I remember fixing an issue when query parameter is an entity (manged,
detached or unmanaged). But can not recollect when (which version), where

If memory serves me right, the fix effectively translates query parameter

Hi Daryl,
All that I can say is that the posting you referenced is almost two years
old and it may have been resolved in the release that you ran against. What
version of OpenJPA did you try to reproduce the problem with? I did a quick
search of our JIRA's to see if this has been resolved, but I
Thanks, Daryl. From your description, I would agree with your assessment.
:-) Could you open a JIRA issue [1] with information from this posting? If
you don't have JIRA access, let me know and I can create it for you.
Thanks,
Kevin

Is this the plugin [1] you are referring to? If so, this extra menu item is
supposed to be used to indicate that you want the Enhancer build step to be

Here's another idea... When did these entities get persisted to the
database? And, are they still part of the persistence context that is being
used for the query? Generated identity fields are not available in the

Yes I just turn on trace logging and then test the query in my SQL tool to
work our what the issue is.

Yes, id I too believe should be without quotes. In any case the query
generated should provide with sufficient information about what is going
wrong.

When I say "eclipse project" I mean I am creating a project in Eclipse, I am
not using Ant and I don't want to use Ant. I tried the OpenJPA plug-in but
it doesn't do anything except add a menu item, I still need to use runtime
enhancement which is a pig of a thing.

Also, you could try removing single quotes from your JPQL string:
"Select c from Platform c where c.id = 8"

What do you mean by eclipse project? It sounds like you may have

Normally I setup an ant builder[1] when running in Eclipse.

Try turning on SQL trace to see what SQL is being generated from your
JPQL.

Hi all,
I wrote this query here.
select o from User as o
where o.id in (
select valueInteger from UserPersistentParameter as o
)
but I got

Hey,
Through some wacky querying I came across this:
http://n2.nabble.com/Persistent-entities-pass-as-params-to-JPQL-queries-MUST-be-attached-Query-getSingleResult-bug-or-exp-td209033.html
I tried to verify this but could not. Here's a simple attempt:
User user = new User();
user.setId(userId);

GenerationType.IDENTITY appears to make no difference. However, suprisingly

Hi,
How is it dependent upon GenerationType ? As per the doc, "IDENTITY" means
value generated by database upon insertion and "AUTO" means openjpa will
decide the value.
Someone please throw some light .
thanks

Did you try GenerationType.IDENTITY ?
@GeneratedValue(strategy = GenerationType.IDENTITY)
I think it should work with int but I prefer long instead.
