IMO, the @OneToMany annotation should not be used for collections of value-typed objects.
-----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Emmanuel Bernard Sent: Sunday, November 20, 2005 3:41 AM To: Hibernate development Subject: [Hibernate] specific annotation for collection of elements It started from turin42: i read the spec and the docs and i've got a hard time explaining the abuse of @OneToMany is this how it is going to look like in EJB 3.1? epbernard: Nothing is specified for such things in EJB3 nor even globally designed What do you mean by @OneToMany abuse turin42: @OneToMany on a collection of strings conflicts with our explanation of one-to-many _entity_ associations i think a separate set of annotations would be better epbernard: I wanted the spec commity to rename targetEntity by targetElement turin42: that would have been a first step but still, i think the completely different semantics of whats _inside_ that collection deserve different annotations lifecycle, shared references, identity, etc. i would reserve *-to-* only for entity associations thats what we have always done in hibernate keep in mind that this stuff is the most difficult thing to understand in ORM also, we use @Embedded and not @OneToOne what about a @org.hibernate.annotations.CollectionEmbedded supporting @JoinTable and @AttributeOverride But actually, you can do @CollectionEmbedded @Embedded public Set<Address> getAddresses(); or @CollectionEmbedded //no embedded here so address will be stored in its serialized form public Set<Address> getAddresses(); So I'm not so happy of the @CollectionEmbedded name (the fact that embedded is inside), WDY all T? @CollectionElement, @ElementCollection? ------------------------------------------------------- This SF.Net email is sponsored by the JBoss Inc.
