Hi Pinaki,
OpenJPA 2.1.0-SNAPSHOT didn't help.
I also made a separate sample with a Message, AbstractMessage and Header
(a message has many headers).
I defined:
- @OneToMany(mappedBy...) with type Header on the AbstractMessage
- @ManyToOne with type AbstractMessage on the Header.
With that config, the FK is not created (nor the corresponding
message_id column in Header table). I receive no exception.
Another question was the definition of indexes: Does JPA standard
provide this ?
Tks,
Eric

Hi Pinaki,
We use the maven downloaded jar release 422266:935683 from
22-Apr-2010, so we don't have the patch for the MappedSuperClass.
I didn't find a recent 2.0.0-SNAPSHOT on
http://people.apache.org/maven-snapshot-repository/ nor on
https://repository.apache.org/index.html.
Will try with 2.1.0-SNAPSHOT.
The entites can be found here:

Hi,
The "mappedBy" mapping on abstract class should work and the
relations need
not be redefined in the concrete subclass.
But a critical bug on MappedSuperclass had been found recently --
which *may
be* impacting the mapping.
1. Which OpenJPA revision being used?
$ java -jar /path/to/openjpa.jar
shows the revision number.
2. If the used revision is prior to 952893 (dated June 8,2010), is it
possible to switch to a post-952893 version and see if that resolves the
issue?
3. Can you please post the relevant entity classes (JPAMesaage etc.) for
further analysis?
