Question

The spec says that CDI container removes a SFSB when the scope’s context is about to be destroyed. How does it exactly remove the EJB? It does not seem to be calling the method annotated with @Remove.

@Stateful
public class CustomerDAOImpl implements CustomerDAO {
    @PreDestroy
    public void onDestroy() {
        //This is getting called as expected
    }
    @Remove
    public void deleteMyBean() {
        //This is not getting called!
    }
}

So, CDI is technically doing what the spec says. The question is how is it managing to ask the EJB container to remove the instance? Thanks.

As covener says this is done using an implementation specific EJB API, that isn’t part of the EJB standard API.

As covener says, calling @Remove is NOT the right way to proceed. @Remove methods are called by users code, and tell the EJB container to remove the EJB. If you want a callback when the EJB is removed, use @PreDestroy.
