Assuming it was... have a look at this:
https://github.com/wsmoak/zookeeper/tree/master/simple-watch
I'm not entirely sure about a couple of things, but at least it runs
and behaves as described.
Hope that helps! And just ask if something doesn't work or doesn't make sense.

... and, here it is again with a Maven build:
https://github.com/wsmoak/zookeeper/tree/master/simple-watch-mvn
(If you're at a Windows command line, I imagine you'll need to give it
a different "program" to run as the bash script won't work. Change
the exec plugin config to do that, or ask if you get stuck.)

So that you can see the start, stop, and restart behavior, I updated
this to use a trivial 'program' (bash script) that counts up 1, 2, 3,
with a five second delay.
https://github.com/wsmoak/zookeeper/tree/master/simple-watch
Here is what it might look like:
(In the command line interface)
[zk: localhost:2181(CONNECTED) 16] create /stuff my_data
Created /stuff
[zk: localhost:2181(CONNECTED) 17] set /stuff other_data
[zk: localhost:2181(CONNECTED) 18] delete /stuff
(running the watcher example)

If you look at
https://github.com/wsmoak/zookeeper/blob/master/simple-watch/run.sh
you can see the minimal set of things I had to add to the CLASSPATH.
zookeeper-3.5.0-alpha.jar
slf4j-api-1.7.5.jar
slf4j-log4j12-1.7.5.jar
log4j-1.2.16.jar
The logging jars were not needed to compile the project, but they are
needed to run it.
The next thing you might run into is a complaint about configuring
Log4j. There is a sample config file in the conf/ directory of the
ZooKeeper .tar.gz distribution.

Have you added the slf4j on your classpath?

Hi Wendy,
thank you for taking an effort to try and making it work.
As I tried earlier, I used eclipse IDE and gave following arguments in run
config:
localhost /stuff output.txt ls
so encountered following error.
Exception in thread "main" java.lang.NoClassDefFoundError:
org/slf4j/LoggerFactory
at org.apache.zookeeper.ZooKeeper.<clinit>(ZooKeeper.java:94)
at Executor.<init>(Executor.java:38)
