About EJB Finder View Objects

EJB finder view objects are classes, paired with XML files, that implement the J2EE Value List Handler pattern. EJB finder view objects are factories for collections of EJB entity facades.

EJB finder view objects are very similar to BC4J view objects. In particular:

• EJB finder view objects implement the interface oracle.jbo.ViewObject, allowing you access to the view object API.
• EJB finder view objects can be used as datasources for any type of client (such as BC4J JSP) that can use BC4J view objects.

However, EJB entity facades are different from BC4J view objects in some important ways:

• Instead of being based on SQL queries, EJB finder view objects are based on EJB finder methods. An EJB finder view object's result set will contain EJB entity facades corresponding to all EJB entity beans returned by the finder.
• The rows returned by EJB finder view objects' navigation methods are EJB entity facades, not view rows.
