Question

Is there any way to know when a war is being hot deployed so I can shutdown the old executor that is running scheduled tasks? I’m using jboss 6 and I have a scheduled thread pool that is updating data periodically in the background. When I hot deploy that thread pool is not shutdown and new starts up so I have multiple scheduled thread pools.

Thanks for any input.

Yes, but it depends on where you start your Executor and which technology you use:

• in ServletContextListener: start Executor in contextInitialized() and shut it down in contextDestroyed().

• in servlet, start Executor in init(), shut it down with destroy()

• in EJB/Spring bean: start in method annotated with @PostConstruct, shutdown in @PreDestroy.
