Dear JPA Specialists,

I need your advice on getting a OneToMany (Employee to Photo) relational mapping using @ElementCollection & @CollectionTable in JPA 2.0. Below is a hypothetical code snippet that I am trying to get all the Photo records persisted without success:



However, only the last photo (afterWorkPhoto) object has been persisted to the Employee entity instead of all 3 photos. I also want the option of going back to add more new (unique) photos for the same employee in the future.

I am running Eclipselink 2.4.1 (JPA 2.0), Java 7 on Windows XP & 7.

Your advice would be much appreciated.

Thanks in advance,

Jack

In your code you call createEmployee with an Employee but your code takes String, String, ..., so what you posted is not the real code.
Your createEmployee seems to be creating a new Employee, so make sure you are adding the photos to that employee.

Also, your addPhotos method first does a contains, ensure that your equals and hashCode methods are correct.
