Hi,
I have a requirement as mentioned below:
Table A has a column COL1 of type VARCHAR2, table B has column COL2 of type
NUMBER. When i provide the COL2 as join column for the @OneToMany
annotations OpenJPA is throwing an exception for type mismatch. Is there any
work around or solution to type
I tried the persistence.xml entry, didn't help... I'm just not sure how to
develop in the dark like this with no useful error message... this isn't the
first time I've gotten that generic error either.
This is just terrible.

I've see in these cases that it's hard to get the details of what went
wrong since the error is being reported to you at commit time while
the error actually occurred earlier.
Getting the earlier stack trace is what is needed, and this requires
some coordination between WebLogic and OpenJPA
Hi,
The stack trace posted here points to no OpenJPAException. A
OpenJPAException often carry the nested throwables. But in a long JEE stack
who knows who is swallowing whose exceptions?
Going by the javadoc of the application-visible
weblogic.transaction.RollbackException, there are two met
Hi,
I've never used WebLogic, so I can't help with specifics. I'd guess that
there was a nested SQLException. Turning on OpenJPA SQL trace might help. In
JSE you can do this by adding a property to persistence.xml :
WebLogic may have other ways to enable OpenJPA's SQL trace (quick googling
didn'
Yeah I saw those; but in tracing down into the code, I can see that an
exception actually never gets thrown. What I get is an exception from
weblogic like this:
Feb 23, 2009 5:00:01 PM CST>
org.apache.openjpa.util.StoreException: The transaction has been rolled
back. See the nested exception
The OpenJPA StoreException class has a "type" property that may provide
you additional information. Make sure also that you're printing out the
stack trace of the nested exception.
Check out the JavaDoc for the exception class:
http://openjpa.apache.org/builds/1.2.0/apache-openjpa-1.2.0/docs/javad
The problem is that it isn't telling me "why" the transaction has been rolled
back; for example the way you do if you try and insert a null value into a
non-nullable column etc, you typically get a jdbc error. I'm getting zero...

Obviously, I've done that; it's on a single line of code, the persist method of
the entity manager. The object graph looks good as far as I can tell.

I'm having a very difficult time with OpenJPA (via weblogic).
I often get a strack trace that doesn't help me at all, it just looks like
this:
"org.apache.openjpa.util.StoreException: The transaction has been rolled
back. See the nested exceptions for details on the errors that occurred."

Hi all,
I have a problem when trying to find objects of a base-class by using a
field from one of the subclasses in the where-clause.
The error I get is a 'No field named "xxx" in class "yyy"'. Hibernate
resolves this kind of query but OpenJPA obviously does not.
Example:
Base-class:
import jav
Hi,
Excellent!
Do I have a vote? (In most places, I don't).
If I do, then +1.

Hi,

I had put a fix for this issue recently OPENJPA-935.
Will the original reporter please verify?
OpenJPA makes a decision during bulk delete whether the delete operation
involves a single table only. That decision was not accounting for cascade
behavior for embedded fields.

Yup, I agree.
Did this separate subproject require approval from Apache Board?

If you are saying we should make this stuff part of openjpa officially
(meaning some new openjpa-eclipse module) then I have some concerns.
I am not con
For Geronimo, we also setup a Devtools subproject for our Eclipse
plugins. I would suggest doing that for OpenJPA, as the maven builds
are different enough that you don't want non-Eclipse users to deal with
the delays of downloading an Eclipse runtime for the build steps. Also,
you may want t

Hi Kevin,
Why I considered starting to build a plugin for OpenJPA is two-fold:
a) to estimate and experience first hand, what is the complexity involved in
developing a Eclipse based tooling for OpenJPA with this prototype. Starting
as a novice, the effort was equivalent to 4 person-days.
b)
Hi Philip,
Yup, I agree with your argument, and it seems to me the conclusion shows
that our example (either mine or the original one that you proposed and
I expanded) doesn't really mirror what a bank would do. If it dispensed

Hi Pinaki,
Thanks for starting this activity. I've noticed that OpenEJB has a separate
project for the OpenEJB Eclipse Plugin. Maybe we should consider following
the same path? Not sure if it's a lot of overhead to have a separate
project like that or not.
Thoughts?

Hi,
For Eclipse IDE users, a plugin is available to help development with
OpenJPA [1]. It adds a builder step to Java projects in Eclipse workspace so
that all your persistent classes are bytecode enhanced as part of the
Eclipse's incremental compilation process.
Please note that, at this point
