Hibernate - How to remove entity from parent when deleting child

Hibernate ORM
8

I update the code and make my problem more self explaining.

I added a folder to the entities.

Now if I what to correctly delete a project I have to do it like that:

		folder.getProjects().remove(project);
		user.getProjects().remove(project);
		project.setOwner(null);
		project.setFolder(null);
		entityManager.remove(project);

This is really annoying as I have to think about adding two more lines for the next OneToMany association.
