Configuring a Life Cycle Callback Method for an EJB 2.1 Session Bean

The following are the EJB 2.1 life cycle methods, as specified in the javax.ejb.SessionBean interface, that a session bean must implement (see "Using Java"):

• ejbCreate

• ejbActivate (stateful session beans only)

• ejbPassivate (stateful session beans only)

• ejbRemove

• setSessionContext

Note:

Using EJB 2.1, you must implement all session bean callback methods. If you do not need to take any action, or if the callback method does not apply to your session bean, implement an empty method.

For more information, see the following:

• "What is the Stateless Session Bean Life Cycle?"

• "What is the Life Cycle of a Stateful Session Bean?"

Using Java

Example 12-1 shows how to implement an EBJ 2.1 session bean callback method.

public void ejbActivate() {
    // when bean is activated
}
