Hi,
You might want to add @ElementDependent as shown below:
@OneToMany(cascade = CascadeType.ALL, fetch = FetchType.LAZY,
mappedBy = "parent")
@OrderBy(value = "ordr")
@ElementDependent
private List<Child> children = new ArrayList<Child>();
so that when you do:
em.getTransaction().begin();
parent.removeChildren();
em.flush();
em.getTransaction().commit();
the children will be removed from the database.
