Observe shutdown of a seam application

heffner Jun 17, 2008 11:26 AM

I'm using an observer class annotated like this:

    @Observer("org.jboss.seam.postInitialization")
    public void seamInitialized() {
        // doing many things with Seam components :-)
    }

Works fine as expected.

But, I would also like to know when the application stops or will be restarted. Within the Seam Sources I havn't found any Event like "preShutdown".

I've tried to solve this using a MBean, but there I can't use the Seam components.

Is there any way to get notified within the Seam application context?

Hi,
My proposed solution would be

@Name("applicationLifecycle")
@Startup
@Scope(ScopeType.APPLICATION)
public class ApplicationLifecycle {

     @Logger
     Log logger;

     public ApplicationLifecycle() {
     }

     @Create
     public void onCreate() {
          logger.info("applicationLifecycle started");
     }

     @Observer("org.jboss.seam.preDestroyContext." + "APPLICATION")
     public void onDestroy() {
     }

}

Many thanks! I tried that approach before but made a mistake setting the Scope.
