Hi,

I use Hibernate 3.6.4 with JPA 2 .
I have OneToMany similar to the below code:

1. Parent Class:

@Entity
@Table(name = "PARENT_TABLE")
public class Parent implements Serializable{

@Id
@GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "SEQ_IC_PARENT")
@SequenceGenerator(name = "SEQ_IC_PARENT", sequenceName = "SEQ_IC_PARENT", allocationSize = 1)
@Column(name = "PARENT_ID")
private Integer parentId;

@Column(name = "PARENT_NAME")
private String parentName;

@OneToMany(mappedBy="parent",
targetEntity = Child.class, cascade = { CascadeType.PERSIST, CascadeType.MERGE,CascadeType.REMOVE,CascadeType.DETACH,CascadeType.REMOVE,CascadeType.REFRESH},
orphanRemoval=true)
@Cascade( { org.hibernate.annotations.CascadeType.SAVE_UPDATE,
org.hibernate.annotations.CascadeType.MERGE,
org.hibernate.annotations.CascadeType.DELETE,
org.hibernate.annotations.CascadeType.PERSIST,
org.hibernate.annotations.CascadeType.DELETE,
org.hibernate.annotations.CascadeType.DELETE_ORPHAN })
private List<Child> ChildList = null;

}

2. Child Class

@Entity
@Table(name = "CHILD")
public class Child implements Serializable{
@Id
@Column(name="CHILD_ID")
private String childId;
}

3. Parent Child Class:

@Entity
@Table(name = "PARENT_CHILD")
public class ParentChild implements Serializable{

@Id
@GeneratedValue(strategy=GenerationType.SEQUENCE, generator ="SEQ_IC_BD_SUPPORT")
@SequenceGenerator(name="SEQ_PARENT_CHILD", sequenceName="SEQ_PARENT_CHILD", allocationSize=1 )
@Column(name = "PARENT_CHILD_ID")
private Integer parentChildId;

@ManyToOne
@JoinColumn(name = "parent_id",insertable=false,updatable=false)
private Parent parent;

@OneToOne
@JoinColumn(name = "USER_ID")
private Child child;
}

Basically I have 3 tables. Parent, Child and Parent_Child.

When saving the list in parent class, the child records are not deleted when i remove them from the collection.

Can you let me know If I am missing any in the mapping?

On Save I do this:

transaction = session.beginTransaction();
session.save(parent); or session.update(parent);
session.flush();
transaction.commit();
