Hi,
I've written a test helper class that starts up ZK in-process and tears =
it down when done.  Here's a code snippet:

 static NIOServerCnxnFactory _standaloneServerFactory;
 public static int _clientPort =3D 21818;
 static ZooKeeperServer _server;
 =20
 _server =3D new ZooKeeperServer(dir, dir, tickTime);
 _standaloneServerFactory =3D new NIOServerCnxnFactory();
 _standaloneServerFactory.configure(new InetSocketAddress(_clientPort), =
numConnections);
 _standaloneServerFactory.startup(_server);

One thing I've noticed is that the final line appears to be synchronous =
in nature, whenever I attempt to connect to ZK immediately, my client =
fails.  Currently, I just retry a few times.  Is there a programmatic =
way to check when the server is read for connections?  I tried a few =
method calls on ZooKeeperServer but nothing was helpful there.

Thanks,
Adam=20=
