I'm a little confused - it sounds like you are trying to read the values in
order to respond to a subscription (subscribe request), but you are doing
the read in initializeCompleted(). It seems like you would really want to
do this by extending the SubscriptionManager capability
(org.apache.muse.ws.notification.impl.SimpleSubscriptionManager),
overriding initializeCompleted() and use the value of the subscription's
topic to figure out what steps to take next (SubscriptionManager.getFilter
() will return a TopicFilter if you're subscribing to topics). This is
different than trying to add a capability to the producer resource (which
creates the subscriptions).
