Thank you for answering. I'm not sure I understand the question properly. I think the descriptors did get generated. It wasn't a requirement, just the way I run the generator. I added the -nodesc flag and now I have the mapping (attached) and the descriptors are gone.
But when I try to use it I get the MappingException "Could not find the class
nikonpromosystem.PromoCall", even though the package is listed in the source
packages in my project, and the PromoCall class is in there. Note that the
declaration of PromoCall works, so the class is visible.
Here's my code:
nikonpromosystem.PromoCall promocall;
Mapping mapping = new Mapping();
URL url1 = this.getClass().getClassLoader().getResource("binding/promomap.xml");
mapping.loadMapping(url1);
Unmarshaller unmarshaller = new Unmarshaller(promocall.getClass());
unmarshaller.setMapping(mapping); //error occurs here
I also tried defining promocall as nikonpromosystem.PromoCallType, but I got
the same error.

Hi Lukasz,
before trying to answer your questions (inline, that is), can I ask you
something ? What's the reason to generate Java classes from your XML
schema without descriptor classes (instead of a mapping file) ? I just
would like to understand this requirement.
Cheers

In addition to the -gen-mapping option you will have to use the -nodesc
option.

Yes, this is default. When you start using the -nodesc option, the
descriptors packages will disappear.

Hi, if you did not use this with the mapping file(that did not get
generated), there is no use trying this, as the XML
generated/unmarshalled from will not meet the XML schema. You will have
to use either the mapping generated and or the XML class descriptors.
