EJB 3.0 relationship mapping fail to remove foreign table record

Question

I have a Customer class which declare the relationship as follow:
@OneToMany(cascade={CascadeType.ALL}, mappedBy="book")
private List<Book> book;
At my Phone class I declare the relationship as follow:
@ManyToOne
private Customer customer;
Whenever I remove the a book, the book is being removed as I iterate the List<Book> collection using the get method. But in the database, the records still exist!
Anyone can explain where has gone wrong?

Answer 1

Try flushing the entity manager directly after removing the book. But i think the book will still remain as you are not calling the remove method. In your case the relation maybe removed. you have to remove the book from the book class itself.
