I extend the ServletContextListener and I inject the spring service bean in it.

@ManagedProperty(value = "#{PersonManager}")
private PersonManager personManager;

I got NullPointerException when I used the personManager instance in the contextInitialized(). I would like to know is that possible to look-up the spring service bean instance in the my ServletContextListener. And I would like to know is there any way to look-up the spring service bean in the ServletContextListener.

Where is that bean declared? How is it loaded and initialized? – Sotirios Delimanolis Jul 03 '14 at 06:50
I used `` in the applicationContext.xml which is in the WEB-INF folder. – user1156041 Jul 03 '14 at 06:54
And what relation is there between `@ManagedProperty` and that `applicationContext`? – Sotirios Delimanolis Jul 03 '14 at 06:55
I add the spring listener in the web.xml. `org.springframework.web.context.ContextLoaderListener` and `org.springframework.web.context.request.RequestContextListener` – user1156041 Jul 03 '14 at 06:58
What is _the spring listener_? Show us. How is `@ManagedProperty` related to this spring listener? – Sotirios Delimanolis Jul 03 '14 at 06:59
I can used the `@ManagedProperty` in the backing bean. But I got `NullPointerException` in `ServletContextListener` and `Filter`. – user1156041 Jul 03 '14 at 07:04
You're not answering my question. Once you look into that, you'll understand what is wrong. – Sotirios Delimanolis Jul 03 '14 at 07:06
