for 3 days, I’m stuck on this problem, I try to explain as clearly as possible:
I’m working on a software inventory management, I use EclipseLink(JPA2.0) for managing the Database.
the problem is that when I create a new invoice with related Articles
, and try to persist them, then i get a Referential integrity constraint violation Exception…
the real problem is that I generated all entities with netbeans(since I’m not familiar with the annotation)
and I can not confirm if they are correctly generated or not(but still I doubt)….

tomorrow I will try with another DBMS, to avoid conflict…
PS: Im Sorry for french language..I have no choice.
UPDATE:
its worked :
EntityManager em= emf.createEntityManager();
em.getTransaction().begin();
em.persist(fact);
em.flush();
for(FactProformaHasArticle couple: estComposeFacture)
{
couple.getFactProformaHasArticlePK().setFactProformaIdfactProforma(fact.getIdfactProforma());
em.persist(couple);
}
em.getTransaction().commit();
You already have a solution but I thought I’d mention the reason why it works is because you have the primary key field controled through the EmbeddedId’s basic mapping – so even though you may have set the relationship before persisting, the pk field will be null until the embeddedId’s articleIdarticle is set with a value manually. This is the problem with having the “ARTICLE_IDARTICLE” mapped twice – both mappings should be maintained by the application, and the pk value needs to be available before you persist FactProformaHasArticle.
JPA 2.0 makes this setup a bit easier, as you can use the @MapsId annotation on the relationship to show that it controls the embeddedId’s basic mapping – so you only need to set the relationship and have JPA set the field for you. Or you can remove the embeddedId, use the object as a PKclass and mark the relationship with @Id directly as described here:
http://en.wikibooks.org/wiki/Java_Persistence/Identity_and_Sequencing#JPA_2.0
Using this will allow you to remove the flush call, as JPA will set the pk values for you.
