Hi,
I'm new to JEE world so please forgive all the rookie mistakes en route to
enlightenment. Firstly I completed the 5-minute tutorial. Now I'm trying to
create a MDB (EJB 3 style). I'm following the 5-min-example deployment style
(create EAR project and include EJB project in it).
Now I'm stuck with an exception that I can't understand. Here's what I have
done so far (within EJB project):
* From EJB project, I deleted the openejb-jar.xml (as per 5-min-example).
* Created a MDB called ChatRoomMDB, here's the contents:
package sample;
import javax.annotation.Resource;
import javax.ejb.ActivationConfigProperty;
import javax.ejb.MessageDriven;
import javax.ejb.MessageDrivenContext;
import javax.jms.Message;
import javax.jms.MessageListener;
@MessageDriven (activationConfig =
{
@ActivationConfigProperty(propertyName="destinationType", propertyValue="
javax.jms.Queue"),
@ActivationConfigProperty(propertyName="destination",
propertyValue="SendReceiveQueue")
})
public class ChatRoomMDB implements MessageListener {
private static final long serialVersionUID = 1L;
@Resource
private MessageDrivenContext mdc;
@Override
public void onMessage(Message msg) {
System.out.println("Rcv: " + msg);
}
}
When I try to deploy it in app server (Geronimo 2.1 server integrated into
Eclipse with Geronimo v2.0 Server Adapter 2.0.0) I get the following:
19:01:34,703 ERROR [GBeanInstanceState] Error while starting; GBean is now
