EJB types and their definition
In EJB 3.0 there are two types of EJB:
Session beans (stateless and stateful)
Message driven beans
Note: EJB2.x entity beans have been replaced by JPA entities, which are discussed in Chapter | 2, Persistence using the Java Persistence API (JPA).
Next we describe how annotations can be used to declare session beans and MDB beans.
