Shutdown hook issue

[danydyn]

Hi,

I am running a spring based application in Jboss web container.

I use the system property -Djboss.shutdown.forceHalt=false.

I registered a jvm shutdown hook in one of my bean's init method using Runtime.addShutdownHook.

This shutdown hook runs indeed when I stop the server, but I found out that if I halt the hook's execution, like

by putting a breakpoint in it, eventually the jvm terminates, although I defined the system property above. (JVM should wait for all shutdown hooks to complete).

Any explanation for this paranormal behaviour?

Thanks

Daniel.

Interesting approach to solve the problem. Have you checked if it's an issue related with the IDE you're using ?

As an alternative, you might consider registering an MBean:

public class StartupService extends

                        ServiceMBeanSupport implements StartupServiceMBean {

    public StartupService() { }            

    . . . .

    @Override

    protected void stopService() throws Exception {

          log.info("[StartupService ] Stopping Startup Mbean");

    }

}

stopService should kick in when the shutdown of the server is in progress.....

hope it helps,

Francesco

Thank you for answering,

I use MyEclipse, it just calls org.Jboss.Shutdown with --shutdown argument.

I'll give the JMX approach a try, but still, I'm puzzled...

I loaded the server from command line with run.bat, stopped it with ctrl-c in the console,

and guess what... it did not halt.

Which means that probably the problem lyes with myeclipse.

Thank you Fransesco for pointing it up for me.

glad it helped.

By the way, I had a peaceful morning so I had time to write a small article on my blog about it :

I would also suggest the context listener approach - implement ServletContextListener and override contextDestroyed method.
