@Id and @AttributeOverride [message #945187] Mon, 15 October 2012 05:30 Go to next message
Eclipse UserFriend
I have an abstract class annotated as @MappedSuperclass with attribute @Id and an @Entity class that inherits from that abstract class. I want to use the attribute from the superclass in the inherited class and override the column's name in the database. I did it as follows in orm.xml:

<entity-mappings ...

<mapped-superclass class="abstract.SuperClass">
   ...  
   <attributes>
      <id name="id"><generated-value strategy="AUTO"/></id>
      ...
   </attributes>
</mapped-superclass>

<entity class="entity.InheritedClass" access="FIELD">
   ...
   <attribute-override name="id"><column name="INHERITED_CLASS_ID column-definition="BIGINT"/></attribute-override>
   ...
</entity>


Running this example throws the following exception:

Question: is it not possible to override the attribute @Id? Is it mandatory, that I use for every @Entity an own attribute @Id?

Thank you!

That's interesting, what it is saying is that it doesn't find the id attribute at all (let alone the override).

What happens if you put access="FIELD" on the mapped superclass?

Can you post your model classes as well?

The following tectonics.class is another class, but has the same configuration concerning my problem. eclipselink does not complain here, may be it stops directly after it has found the "error":

I can't see anything wrong with your model. Any chance you could capture the logging and post it? Also looks like you posted TectonicsLevel level twice and not the Tectonics class.

Seems very strange (in that it should work, I see no issues). For sake of testing,
any chance you could try mapping AbstactEntity with an @Id annotation instead (and comment out the mapping from XML)?

I changed the classes as you proposed, there is still the same exception. Is it possible, that overriding the attribute @Id is not allowed? In

http://wiki.eclipse.org/EclipseLink/UserGuide/JPA/Basic_JPA_Development/Entities/MappedSuperclass

there is said:
Quote:
You can use the @AttributeOverride and @AttributeOverrides annotations, or <attribute-override> XML element to override the column for a basic attribute in a mapped superclass. This allows for the column name to be different in each subclass.


Nothing is said about the id attribute can be overridden whereas in

http://www.objectdb.com/api/java/jpa/AttributeOverride

they write that (AttributeOverride is):

Quote:

Used to override the mapping of a Basic (whether explicit or default) property or field or Id property or field.


Strange in any case...

An attribute override is absolutely allowed for an Id mapping, in fact I just tested it myself. Regardless, the fact that the @Id annotation itself is not
found indicates that there is another underlying issues, namely that the mapped superclass is not being found/processed for some reason. Can you elaborate
on your setup a little further? The logging seems to be very reduced as well. With FINEST set in your persistence.xml we should see a lot more output.

Would seem that perhaps you are loading a different persistence.xml and/or orm.xml?

Hi Guy,

I have only one persistence.xml in my whole workspace and there I have set FINEST already. Maybe there is another place where I can extend the logging?

Wait, wait! I got it! The package name of the class AbstractEntity was false! Oh my! Sorry about that! And thank you!
