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开发者_如何学JAVA 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) {
    }

}

The server log said Message Driven Bean cant be managed bean. Well I did not mean it to be managed bean. I did not have @ManagedBean in the code????

EDIT: Here is the server log

The Exception is DeploymentException: Message Driven Beans can't be Managed Beans

This is a bug in GlassFish 3.0 which is fixed in 3.0.1.

  • workaround: remove the beans.xml (but this will disable CDI)
  • real solution: download a promoted build of GlassFish 3.0.1 (the problem is reported as being fixed in version 3.0.1-b9 so any superior version should work)

Below the initial answer:


  • Where is the MDB located? Did you put it in the CustomerApp-ejb?
  • What do you mean by Now I can deploy CustomerApp-war just fine? You're supposed to deploy the Enterprise application (CustomerApp).
  • What do you see in the GlassFish logs when the deployment fails?
