So the same was happening with the release build as well? Why is there 
no class name for the NoClassDefFoundError ?

The following problems may be possible:

1. A JDK conflict (Maybe you need to put ins and the orb jars on the 
bootclasspath so that the classes from those jars override the JDK classes)
2. Another OpenORB jar somewhere where it gets loaded automatically, 
e.g. %JAVA_HOME%\lib\ext
4.  A corrupt jar file

You are the first reporter of such a problem, so I think there is 
something going wrong on your side. I tested your script, but couldn't 
find a problem, but I needed xerces.jar on the classpath. Before I was 
getting a NoClassDefFound org/w3c/Node exception...
