Netbean6.8: Cant deploy an webapp with Message Driven Bean
- by Harry Pham
I create an Enterprise Application CustomerApp that also generated two projects CustomerApp-ejb and CustomerApp-war. In the CustomerApp-ejb, I create a SessionBean call CustomerSessionBean.java as below.
package com.customerapp.ejb;
import javax.ejb.Stateless;
import javax.ejb.LocalBean;
import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;
@Stateless
@LocalBean
public class CustomerSessionBean {
@PersistenceContext(unitName = "CustomerApp-ejbPU")
private EntityManager em;
public void persist(Object object) {
em.persist(object);
}
}
Now I can deploy CustomerApp-war just fine. But as soon as I create a Message Driven Bean, I cant deploy CustomerApp-war anymore. When I create NotificationBean.java (message driven bean), In the project destination option, I click add, and have NotificationQueue for the Destination Name and Destination Type is Queue. Below are the code
package com.customerapp.mdb;
import javax.ejb.ActivationConfigProperty;
import javax.ejb.MessageDriven;
import javax.jms.Message;
import javax.jms.MessageListener;
@MessageDriven(mappedName = "jms/NotificationQueue", activationConfig = {
@ActivationConfigProperty(propertyName = "acknowledgeMode", propertyValue = "Auto-acknowledge"),
@ActivationConfigProperty(propertyName = "destinationType", propertyValue = "javax.jms.Queue")
})
public class NotificationBean implements MessageListener {
public NotificationBean() {
}
public void onMessage(Message message) {
}
}
If I remove the @MessageDriven annotation, then I can deploy the project. Any idea why and how to fix it?
