Simple example for the MDB without configuration file.
package mdb;
import javax.ejb.*;
import javax.jms.*;
import javax.naming.*;
public class MyMDB implements MessageDrivenBean, MessageListener
{
public MyMDB()
{
}
//invoked first after ejbCreate() of MDB
public void setMessageDrivenContext(MessageDrivenContext mdc)
{
}
//invoked first after just object creation of MDB
public void ejbCreate()
{
System.out.println("ejbCreate(): " + this);
}
//this method is invoked when any message arrives on the destination for which this MDB has been configured.
public void onMessage(Message inMessage)
{
try
{
System.out.println("Message received: " + inMessage);
} catch (Exception e)
{
e.printStackTrace();
}
}
//this method invoked when MDB object being destroyed by EJB server
public void ejbRemove()
{
System.out.println("ejbRemove(): " + this);
}
}
