Where's the best place to put code that shutdowns Ehcache CacheManager ? [message #508813]

Hi all,

Our RAP application uses Ehcache caching library which needs to be
shutdown when application exits. The recommended way to shutdown for web
app is by registering ShutdownListener in web.xml.

I was considering the SessionStoreListener, but since Ehcache scope is
supposed to be application wide, I don't think it's the appropriate
place to shutdown when a session is about to be destroyed.

I've tried the Activator#stop(), when I stop the bundle individually
from OSGI console (stop <bundleid> command) it's got called, but if I
shutdown OSGI itself (exit command) it's not.

Any advice would be greatly appreciated.

Regards,

Setya

The exit console command simply does System.exit(0). It is not a safe way to shutdown the framework. Try the close command on the console. Programatically this can be done by calling stop() on the system bundle (the bundle with bundle id 0). This should do proper shutdown of the framework.

I've tried to use close command to shutdown OSGI, but Activator#stop()
didn't get called either.

Sorry for asking an obvious question, did you verify that the Activator#start() method was called? The framework will only call the Activator#stop() method for bundles that are active at the time the framework is shutdown.
