My app provides a System Service, which works well if it is running

Service is failed to be served,
even though my app can be launched normally by the Service request.
Here is the corresponding Console log message:
PM Safari[368] Application XXX never opened its Services port before
the timeout.
But I'm sure that my app has been ready before the timeout which is
the default 30s, since I register
the Service provider in my applicationDidFinishLaunching:
(NSNotification *) after
all the preparation work is done, and the time needed to get to that
point is no more than 15s.
I can't figure out what is missed after perusing the System Service
section of Dev Doc.
Any hint will be appreciated, and any further info will be
supplemented if needed.
Without seeing some code, I can only offer a couple general ideas:
1. Are you sure that applicationDidFinishLaunching:(NSNotification *)
is being called? If you've got your app delegate wired up wrong, then
you'd never receive this notification.
2. Are you passing the right object to -[NSApplication
setServicesProvider:]?
3. Do you implement the proper service method? A typo could be
preventing the service from being found.
