I´m work with JPA and associations. But a "Repository Pattern" isn´t a relationship, is much more. In my Entity Bean, I need execute complex query (by your attribute "Repository"). The implementation of the Repository class is child of EntityHome. I don´t know how instanciate or inject this Repository in the Entity. If not possible, how do work with "Domain Driven Design" in JBoss Seam?
