Unfortunately, I can't get mapped-superclass callbacks to work in Toplink
Essentials or Hibernate EntityManager.
Funny, considering it must be a fairly common requirement.

I've mapped it like this:
<mapped-superclass class="org.permacode.atomic.domain.AtomicEntity"
access="FIELD">
<pre-persist method-name="prePersistCallBack" />
<attributes>
<basic name="ownerId">
<column name="OWNER_ID" />
</basic>
<basic name="created">
<column name="CREATED" />
<temporal>DATE</temporal>
</basic>
<basic name="modified">
<column name="MODIFIED" />
<temporal>DATE</temporal>
</basic>
<version name="version">
<column name="VERSION" />
</version>
</attributes>
</mapped-superclass>
The method prePersistCallBack() is on the superclass:
public void prePersistCallBack()
{
this.modified = new Date();
logger.info("doing prePersistCallBack() - " + this + " - modified="
+ this.modified);
}
I see no logging and I see the SQL statement contains the untouched
modified value.
