I have the following relationship


that has a one-to-one unidirectional relationship to an image





I have other sub classes of the GenericProfile that need to inherit the relationship. I can't make the relationship bi directional because GenericProfile is not an entity. I've tried many variations of the OneToOne annotation on the GenericProfile with no luck. E.g.



I've also searched the forum and saw that it might be possible with a ManyToOne or ManyToMany with the unique attribute set. E.g.



I've seen some posts that seem to indicate that it's impossible and others that say it is possible. Could anyone let me know if this is possible or not and possibly provide some advice on how I might be able to get around it if it is possible?

Thanks

If I understand you correctly, the generic profile table has no reference to the image table, but the image table does to profile. This is a basic and highly used relationship type and Hibernate 3 doesn't support it. H3 only does one-to-one unidirectional from a table to another, so Generic profile would have to have the foreign key id of image. Basically, the including table (or object) has to have the reference, not the other way around. It is most annoying and all the work-arounds are messy.

In my opinion, this is the biggest strike against Hibernate.
