With JAX-WS the event source setup has actually become quiet easy. All you need to do is to subclass your endpoint implementation from AbstractEventSourceEndpoint and a subscription manager from AbstractSubscriptionManagerEndpoint and finally point that implementation to a event source specific WSDL.
