Spring MVC can't autowire collection?

My xml looks like this:

<bean name="subscriberStore" class="java.util.HashSet" scope="singleton"/>

And I have the following code:

@Value("#{subscriberStore}")
private static HashSet<Subscriber> subscriberStore;

However, later in the above class, when I call methods on subscriberStore I get a null pointer exception. I've tried using @Autowired and @Resource in place of @Value .. above but it makes no difference.

Anyone have any ideas why the subscriber store is not getting initialized?

Thanks!

You cannot @Autowire static fields. Consider removing the static modifier, if possible.
