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.

“Our children evaluate themselves based on the opinions we have of them. When we use harsh words, biting comments, and a sarcastic tone of voice, we plant the seeds of self-doubt in their developing minds.... Children who receive a steady diet of these types of messages end up feeling powerless, inadequate, and unimportant. They start to believe that they are bad, and that they can never do enough.”
—Stephanie Martson (20th century)
