JPA CascadeType ALL does not delete orphans

Question

I am having trouble deleting orphan nodes using JPA with the following mapping   OneToMany  cascade   CascadeType ALL  fetch   FetchType EAGER  mappedBy    owner   private List lt Bikes gt  bikes    I am having the issue of the orphaned roles hanging around the database   I can use the annotation org hibernate annotations Cascade Hibernate specific tag but obviously I don t want to tie my solution into a Hibernate implementation   EDIT  It seems JPA 2 0 will include support for this

If you are using it with Hibernate  you ll have to explicitly define the annotation CascadeType DELETE ORPHAN  which can be used in conjunction with JPA CascadeType ALL    If you don t plan to use Hibernate  you ll have to explicitly first delete the child elements and then delete the main record to avoid any orphan records   execution sequence   fetch main row to be deleted  fetch child elements  delete all child elements delete main row  close session   With JPA 2 0  you can now use the option orphanRemoval   true   OneToMany mappedBy  foo   orphanRemoval true

I had the same problem and I wondered why this condition below did not delete the orphans  The list of dishes were not deleted in Hibernate  5 0 3 Final  when I executed a named delete query    OneToMany mappedBy    menuPlan   cascade   CascadeType ALL  orphanRemoval   true  private List lt Dish gt  dishes   new ArrayList lt  gt       Then I remembered that I must not use a named delete query  but the EntityManager  As I used the EntityManager find      method to fetch the entity and then EntityManager remove      to delete it  the dishes were deleted as well

If you are using JPA 2 0  you can now use the orphanRemoval true attribute of the  xxxToMany annotation to remove orphans   Actually  CascadeType DELETE ORPHAN has been deprecated in 3 5 2-Final
