Local Interfaces

The local interfaces for session and entity beans provide support for light weight access from enterprise beans that are local clients. That is, the bean uses a local interface if the bean wants to provide tight coupling with its clients with pass-by-reference semantics. The local interface is a standard Java interface that does not inherit from RMI.

Local interfaces provide the foundation for container managed relationships among entity beans and session beans. The bean uses the local interface to maintain its references to other beans. For example, entity beans use local interfaces to maintain relationships to other entity beans. They also allow session and entity beans to be tightly coupled with their clients. Using local interfaces, beans can also expose their state and use pass-by-reference to pass their state between related bean instances.
