polymorphism

I couldn't figure out how to cleanly do a tag cloud with JPA where each db entity can have many tags.

E.g

Post can have 0 or more Tags User can have 0 or more Tags

Is there a better way in JPA than having to make all the entities subclass something like Taggable abstract class? Where a a Tag entity would reference many Taggables.

thank you
