Q&A
| Q1: | What are the classes and interfaces that make a stateful session bean? |
| A1: | A stateful session bean is an EJB component, which extends two interfaces: a home interface (EJBHome) and a remote interface (EJBObject), and a bean class that implements the SessionBean interface. |
| Q2: | How can the EJB container recognize a bean as being a stateful session bean? |
| A2: | The EJB container distinguishes all types of beans from the standard deployment descriptor ejb-jar.xml. The tag <session> and the subtag <session-type> are used to set the stateful session bean in the deployment descriptor. |
