Well, either it is a primary key then the constraint is that its unique and not null. Or it is a foreign key so that it is either null or refers to a row in the related table. What is Hibernate supposed to do, if you set the user details to null? Then you would also assign null to the primary key which is not allowed. Second problem: If you assign a new user details bean to the user bean you would also change the pk of the user bean that doesn't make sense. So I doubt this would have ever worked. Simply try the @PrimaryKeyJoinColumn. In theory it should do exactly what you want to do. Try this: | @Entity | @Table(name="usuario") | public class UsuarioEJB { | | private Integer id; | private UsuarioDetallesEJB usuarioDetallesEJB ; | | @Id | @Column(name="idUsuario") | public Integer getId() { | | return this.id; | | } | | // setter | | @OneToOne | @PrimaryKeyJoinColumn | public UsuarioDetallesEJB getUsuarioDetallesEJB() { | | return this.id; | | } | | //setter | | } | Regards Felix View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4042619#4042619 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4042619

I just found an old tools.jar sitting in my classpath; removing that has resolved the issue. Thanks for your help along the way.

[JBoss Seam] - Re: Table mapping

by christian.bauer＠jboss.com

I'm guessing that you mean "I don't want to map certain properties of my class". Just put @Transient on these fields (or getter methods, depending where you put @Id). I recommend you get the basic JPA tutorial in the free chapter 2 of the book I advertise in my signature.

[JBoss Seam] - Re: Nested conversations and transaction management

by christian.bauer＠jboss.com

System transactions do not (this is not 100% but I'm not going to explain the special cases) span HTTP requests. TSPL uses two transactions for each JSF request.

Isn't it ? | This can't be the case if you use TSPL. EJB method calls with no transaction annotation will just join the existing transaction(s) controlled by the TSPL.
