Enterprise JavaBeans, Third Edition

EJB 2.0: Package: javax.jms

This package defines the classes and interfaces of the Java Message Service. The MessageListener interface of this package is important to EJB 2.0.

MessageListener

This interface must be implemented by message-driven beans. The onMessage() method is used to deliver JMS Message objects to the message-driven bean at runtime.

public interface MessageListener 
{
    public void onMessage(Message message);
}
