Thank you for working on the hello world examples.

I had problems when running them, though.
Whichever product file I started, an exception like the following was always thrown:

java.lang.NullPointerException
at org.eclipse.ecf.provider.zookeeper.core.internal.Configuration.clean(Configuration.java:220)
at org.eclipse.ecf.provider.zookeeper.core.internal.Configuration.configure(Configuration.java:64)
at org.eclipse.ecf.provider.zookeeper.core.ZooDiscoveryContainer.init(ZooDiscoveryContainer.java:119)
at org.eclipse.ecf.provider.zookeeper.core.ZooDiscoveryContainer.connect(ZooDiscoveryContainer.java:339)
at org.eclipse.ecf.provider.zookeeper.DiscoveryActivator$3.run(DiscoveryActivator.java:136)
at java.lang.Thread.run(Thread.java:619)

Digging a bit through the code I found out that the problem is the setZookeeperData call in Configuration.java:57. It always tried to create the path "/tmpzookeeperData". Of course, it has rights to create a directory in my root.

Adding a "+ File.separatorChar" and thus changing the call to

setZookeeperData(new File(getConfigProperties().get(
ZOOKEEPER_TEMPDIR).toString() + File.separatorChar
+ getConfigProperties().get(ZOOKEEPER_DATADIR)));

fixed the problem.
Forgive me if this is not the right way to inform you of the bug and fix. ;)

Thanks and Regards,
Patrick
