JaxR Sample in Ivan Krizsan's Notes

Hi, i'm preparing for scdjws an try to implement the JaxR Sample from Ivan Krizsan's Notes.
I'm using juddi V2, the complete Tomcat bundle. The Registry Application is running.
But when i'm Running the client code from ivans exam notes (thanks for that)
I get an error when ConnectionFactory.newInstance(); is called.
The new instance is null, because the method provides a null default value and
there is no System Property javax.xml.registry.ConnectionFactoryClass.
Does anyone got the Sample up and running ?
Thanks in advance
Stefan

Hi!
I have tested all the examples in the study notes and did not experience any problems. I did the JAXR part quite some time ago, so I must admit that my memories are slightly blurry now.
Best wishes!
