My domain model is as mentionded below.
Class ChildClass1 extends ParentClass using InheritanceType.JOINED.
Parent class has one-to-one relation with Another class.
DummyClass has onetoone relation with ChildClass1 .
When i try to save Parent object which has childclass1 , Another object and DummyClass object, save operation is failing.
It is executing only insert into ParentClass (Version, ToolDescription, ToolName) values (?, ?, ?) this statement and failing. I am getting below exception.
org.springframework.dao.DataIntegrityViolationException: not-null property references a null or transient value: .tool.actions.Another.parentClass; nested exception is org.hibernate.PropertyValueException: not-null property references a null or transient value:
Could any body please let me know what is the problem with my domain model?

When i do the below operations to save Parent object, it is failing.
HibernateTemplate temp = new HibernateTemplate(getSessionFactory());
ParentClass parent = new ChildClass1();
((ChildClass1) parent).setPlaceHolder("Child1PlaceHolder");
((ChildClass1) parent).setName("Test");
parent.setToolName("Child1Tool");
DummyClass dummyClass = new DummyClass();
dummyClass.setName1("Dummy");
((ChildClass1) parent).setDummyClass(dummyClass);
Another another = new Another();
parent.setAnother(another);
temp.save(parent);
