You can try to catch an JVM shutdown event in this way:

    Runtime.getRuntime().addShutdownHook(new Thread() {

        public void run() {
            System.out.println("BYE BYE");
        }
    });

The other option is to implement ServletContextListener by using @WebListener Annotation. No xml configuration is required in this case.

@WebListener
public class MyLifeCycleListener implements ServletContextListener {

      public void contextInitialized(ServletContextEvent event) {
          //TODO ON START
      }

      public void contextDestroyed(ServletContextEvent event) {
          //TODO ON DESTROY
      }
}
