Hi Tom,
I have a class java, named Descriptor, which gets a description of
services, interfaces, properties and values of UNO_Object on runtime.
This class is still improvement (e.g. NullPointer Exception is not
handed). However I believe it useful.
If you can, you could take a look at this class, what do you think of it?
Regards, Vincenzo.
