JPA persist with OneToMany ManyToOne

I am trying to persist entities with @OneToMany and @ManyToOne relationships.

@OneToMany(mappedBy="customer", cascade=CascadeType.ALL, fetch=FetchType.EAGER)
private Collection<Address> addresses = new LinkedHashSet<Address>();

@ManyToOne
@JoinColumn(name="customer_id", referencedColumnName="customer_id")
private Customer customer;

problem is that it inserts NULL instead of customer_id in the address table.

could you suggest why is that happening.

Thank you in advance.

That probably means that you didn't initialize the customer field of the addresses. If that isn't the solution, then show us your code.
