Cleanup code in Stateless Session Bean when JBoss shuts down

[stwhit]

I've written a simple stateless session bean with the following interface:

@Remote
public interface Foo {
 void sayHello();
}

and the following implementation:

@Stateless
public class FooBean implements Foo {

 @PostConstruct
 public void postConstruct() {
 System.out.println("Inside postConstruct");
 }

 @PreDestroy
 public void preDestroy() {
 System.out.println("Inside preDestroy");
 }

 public void sayHello() {
 System.out.println("Hello world");
 }
}

When I call the sayHello() method from a client, I see the following output:

06:19:16,150 INFO [STDOUT] Inside postConstruct
06:19:16,170 INFO [STDOUT] Hello world

When I shutdown JBoss, however, I do not see "Inside preDestroy" printed to the screen.

So, my question is two-fold:

Does the @PreDestroy callback get called when JBoss is shutdown? (I would have expected it to, but apparently it does not..?)

If @PreDestroy does not get, how/where can I put cleanup code in my beans that will get executed when JBoss shuts down?

Thanks!
