If the interceptor runs fairly late in the chain (like the USER_LOGICAL
phase), you should be able to do something like:
Exchange exchange = msg.getExchange();
BindingOperationInfo bop = exchange.get(BindingOperationInfo.class);
MethodDispatcher md = (MethodDispatcher)
exchange.get(Service.class).get(MethodDispatcher.class.getName());
That should give you the Method that was bound in so you can get the declared
class or the annotations, etc...

With the "default" things, you could do something like:
Endpoint endpoint = exchange.get(Endpoint.class);
Service service = endpoint.getService();
Invoker invoker = service.getInvoker();
((FactoryInvoker)invoker).getServiceObject(exchange);
to get the object. That really will only work if you're dealing with a
singleton though. (which is the default) If you configure in some other
factory (like to use a pool or per-request), then this really won't work. In
that case, you would need to not use an interceptor. Instead, you would need
to subclass the JAXWSMethodInvoker and override the invoke method to muck
with the object right before it invokes the method.
