Add a StateListener . The stateListener will be notified immediately with the current state of the server and then on subsequent server state changes.

There is a possible race condition if you add the listener right after calling start(int) . That is, your listener may be called twice with the "started" state. It is preferable to add the listener before calling start(). Your listener will then be called twice: once with a "!started" state and then again with "started".
