About Developing Applications Using BC4J Entity Facades

BC4J Entity Facades combine EJB persistence with ADF Business Components libraries. This feature allows you to use declarative validation via an associated XML file, and leverages the rich ADF business component development framework. BC4J Entity Facades have no modeling support, limited CMR support, and a smaller feature set compared to true BC4J, but is a viable option if you want to use ADF business components but must use EJBs as your persistence layer.

Applications built using BC4J Entity Facades automatically implement the J2EE design patterns, just as ADF Business Component applications do. The difference is that the persistence layer are EJBs, not business component entity objects. Application development follows the Oracle Application Development Framework (ADF). ADF simplifies the application development process by implementing the MVC design pattern for Web applications.
