Hibernate version:3


I have a simple test case that creates a row, updates another and deletes another. The create works find but the amendment to the second row and the delete don't get to the database.

Session session = HibernateUtil.currentSession();
Transaction transaction = session.beginTransaction();

Person person2 = (Person) session.get(Person.class, "grape");
person2.setName("pip");

Person person3 = (Person) session.get(Person.class, "peach");
session.delete(person3);

session.merge(person);
session.merge(person2);

transaction.commit();
setPerson(person);


I see a comment in the logs saying that it is ignoring the persisten instance: -

[org.hibernate.engine.PersistenceContext] initializing non-lazy collections
[org.hibernate.loader.Loader] done entity load
[org.hibernate.event.def.DefaultDeleteEventListener] deleting a persistent instance
[org.hibernate.event.def.DefaultDeleteEventListener] deleting [com.abc.def.model.Person#banana]
[org.hibernate.impl.SessionImpl] setting cache mode to: GET

[org.hibernate.event.def.AbstractSaveEventListener] persistent instance of: com.abc.def.model.Person
[org.hibernate.event.def.DefaultMergeEventListener] ignoring persistent instance
[org.hibernate.transaction.JDBCTransaction] commit

It looks like

Mapping is: -

<hibernate-mapping>
<class name="com.drkw.scd.model.Person" table="Person">
<id name="Id" access="field" >
<generator class="assigned" />
</id>
<property name="name" access="field" />
</class>
</hibernate-mapping>

It looks like Hibernate is not detecting calls to setters as changing the objects?

I can see 2 problems -

Merge is used for -


Try replacing session.merge(person2) with session.update(person2)

Also, the instance being ignored is of type - com.abc.def.model.Person , but the mapped one is of type - com.drkw.scd.model.Person. The package names and hence the classes are different.

Perhaps you can post your imports as well.
Are you getting any exceptions?
