[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-4602) Metadata-annotations on jointables are unsupported

Metadata-annotations on jointables are unsupported -------------------------------------------------- Key: HHH-4602 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-4602 Project: Hibernate Core Issue Type: New Feature Environment: Hibernate 3.3, Spring 3, JDK 1.6, MySQL 5.0 Reporter: Niklas Saers A jointable in Hibernate is expected to have only two fields, two foreign keys. However, this relationship often has metadata, such as when it was created, and can have discriminators, such as an enum saying what it belongs to. As requested, I've started with a forum post "https://forum.hibernate.org/viewtopic.php?f=1&t=1001044", and to get more input I've crossposted on StackOverflow: "http://stackoverflow.com/questions/1761901/multiple-manytomany-sets-from-one-join-table". The discriminator should be the easy task, but how to think about annotations on relationships is probably the underlying task. The only solution I can think of with Hibernate right now is to make "relationship entities", but that would leave me with a bunch of poorly defined entities, rather than correctly described relationships.
