OK remember I am a new user of netBeans.
However I supressed all the source files fromNet beans. some directory are highly set to a missing org include but it don't stop the process
Howecer I have the same status on this topic. Even without source file, so witn only the jar file the following code is activated
catch( IllegalArgumentException e)
{
e.printStackTrace();
}
and the message in e = specified GDSType Null is unknown.
