How to Read a Diagram of Enterprise JavaBeans

Session, entity and message-driven beans can all be modeled in JDeveloper. Individual modeled session and entity beans are made up of several compartments. For example:

This illustration is described in the text.

Message-driven beans have only a name compartment containing the «message-driven bean» stereotype and the name of the bean.

Relationships can be modeled between entity beans on a diagram. The entity bean at each end of a relationship must be EJB 2.0, with container-managed persistence, and have a local interface.

References can also be created between modeled beans on a diagram.

EJB References can be created from any bean to any other bean with a remote interface.
EJB Local References can be created from any bean to any other bean with a local interface.

Note: References can only be modeled between beans that are inside the current deployment descriptor.
