Having problems running a RTC client outside eclipse

Hi

I have a RTC client which runs fine from inside eclipse.

I export it as a jar, and run it as follows

c:\jazz\jazzdev\jazz\server\jre\bin\java -Djava.ext.dirs=c:/jazz/jazzdev/jazz/server/jdk/jre/lib/ext;c:/jazz/jpjc -jar reqproConnectorClient_v2.jar

I then get the following error....
Exception in thread "main" java.lang.NullPointerException

Any idea what I'm doing wrong ?

Any help much appreciated
