How would i add a shutdown hook (just like the JVM Shutdown Hook) to listen (get notification) when an EJB application is deployed/undeployed (to stop the JMX MServerBean)?

I could use a ServletContextListener, unfortunately this an EJB jar.

    Use @Singleton bean and implement @PreDestroy:

    @Startup
@Singleton
public class HookBean {

    @PreDestroy
    void wholeApplicationShuttingDown {
    }
}

    UPDATE: Just noticed ejb-3.0 tag. @Singleton was added in 3.1. But still maybe you will find it useful.
