Leandro Hermida updated EJB-69:

Attachment: EntityEmbeddable.vsl.patch
> Improved JoinTable annotation for OneToMany associations in EJB3 cartridge
> --------------------------------------------------------------------------

> Key: EJB-69
> URL: http://jira.andromda.org/browse/EJB-69
> Project: EJB Cartridge
> Type: Improvement
> Reporter: Leandro Hermida
> Assignee: Vance Karimi
> Priority: Minor
> Attachments: EntityEmbeddable.vsl.patch
>
> Hi,
> Here is another patch to EntityEmbeddable.vsl which improves the @JoinTable
> annotation for OneToMany associations in the EJB3 cartridge. For the typical
> example in UML:
> User 0..1 ---------------------> 0..* Security
> The existing EntityEmbeddable.vsl creates an annotation like this in the
> Document.java entity bean class:
> @javax.persistence.OneToMany()
> @javax.persistence.JoinTable(name = "USER2SECURITIES")
> ...
> This is ok as a minimum but if you want to control more details of the join
> table via JoinColumn annotations? You can't. And sometimes the underlying
> persistence provider (like Hibernate) will create weird column names
> especially if you have a given the association end a name. So I added the
> capability for OneToMany just like it is for the ManyToMany annotations:
> @javax.persistence.OneToMany()
> @javax.persistence.JoinTable(
> name = "USER2SECURITIES",
> joinColumns = [EMAIL PROTECTED](name = "USER_ID", referencedColumnName =
> "ID")},
> inverseJoinColumns = [EMAIL PROTECTED](name = "SECURITY_ID",
> referencedColumnName = "ID")}
> )
> ...
