@PreDestroy not working..?

[delley]

Hi,

Im using a jboss 4.0.4GA with jboss-EJB-3.0_RC8-FD installed.

I have a MDB that needs to do some cleaning before it is garbage collected.

I have tried using @PreDestory or similar - but it doesnt seem like its ever being called!?!

I have tried to deploy a new version of the code. Still nothing happend. I tried to shutdown jboss - nothing happend. Or at least no log statment in my logs. And it cant be my logging - have tested it and I know that it is working!

I've read somewhere in this forum that @PreDestroy was moved from javax.ejb to javax.annotation. But as you can see from my import statment I'm using the correct one.

And the library jboss-ejb3x.jar that contains the class is present in <jboss_home>\server\all\deploy\ejb3.deployer\ so it should be loaded - right?

And yes - i'm starting jboss with the -c all switch ;-)

import javax.annotation.PreDestroy;
import javax.ejb.ActivationConfigProperty;
import javax.ejb.MessageDriven;
import javax.jms.Message;
import javax.jms.MessageListener;
import javax.jms.ObjectMessage;
import javax.jms.JMSException;

import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;

@MessageDriven (activationConfig =
{
 @ActivationConfigProperty(propertyName="destinationType",
 propertyValue="javax.jms.Queue"),
 @ActivationConfigProperty(propertyName="destination",
 propertyValue="queue/wipqueue")
})
public class TestMBean implements MessageListener{

 /** Logger. */
 private static final Log log_ = LogFactory.getLog(TestMBean.class
 .getName());

 public void onMessage(Message message) {
 //do something here...
 }

 @PreDestroy
 public void preDestroy(){
 log_.debug("preDestroy called!!!");
 }

}//end class

Any ideas?

Regards,

Im having a very similar problem with MD Pojo's:
http://www.jboss.org/index.html?module=bb&op=viewtopic&t=92593

tried to solve the issue by upgrading to jboss-EJB-3.0_RC9-FD.

Now I cant even deploy my MDB...getting following exception (sigh):


java.lang.RuntimeException: unable to determine messagingType interface for MDB

Mhm, spent some more hours on this problem.

Im now using very very basic SLSB's, and i still cant get @PreDestroy working. Any hints?

package ...;

..
import javax.ejb.Stateless;
import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;
...
import javax.annotation.PostConstruct;
import javax.annotation.PreDestroy;

@Stateless
public class RankingBean implements Ranking {

 @PersistenceContext(unitName="...")
 protected EntityManager em;

 public void keke(){}

 @PostConstruct
 public void thisOneWorksFine() {
 System.err.println("PostConstruct.");

 }

 @PreDestroy
 public void thisOneNeverGetsCalled() {
 System.err.println("PreDestroy.");
 }
}

and

package ...;

import javax.ejb.Local;

...

@Local
public interface Ranking {

public void keke();

}

I wasted lots(!) of time on this, and i'm really clueless what might be the reason for the problem. I'd appreciate any help a lot ;)

Add a method and annotate it with @Remove. See if the PreDestroy gets invoked before the ejb remove is called.

Method annotated with @Remove isnt called either.
