Configuring a Life Cycle Callback Method for an EJB 2.1 MDB

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

• ejbCreate

• ejbRemove

Note:

Using EJB 2.1, you must implement all message-driven bean callback methods. If you do not need to take any action, implement an empty method.

For more information, see "What is the Life Cycle of a Message-Driven Bean?".

Using Java

Example 18-7 shows how to implement an EBJ 2.1 message-driven bean life cycle callback method.

public void ejbRemove() {
    // when bean is removed
}
