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
Werner

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.
