We had discussed entity EJB 3.0 entity relationships in Chapter 7 , Creating EJB
3.0 Entity Relationships , too. In this chapter, we discussed how the EJB 3.0 entity
relationships may be mapped using JSF user interfaces to input data. We created
three entities Edition , Section , and Article with one-to-many relationships
between the Edition and Section entities, and one-to-many relationships between
the Section and Article entities. Subsequently, we created JSF user interface pages to
create Edition , Section , and Article entity instances. When creating the entities,
we also added the mappings between the entities.
