Types of Enterprise Beans
An EJB container holds two major types of beans:
- Session Beans that can be either "Stateful", "Stateless" or "Singleton" and can be accessed via either a Local (same JVM) or Remote (different JVM) interface or directly without an interface, in which case local semantics apply. All session beans support asynchronous execution for all views (local/remote/no-interface).
- Message Driven Beans (also known as MDBs or Message Beans). MDBs also support asynchronous execution, but via a messaging paradigm.
