To be complete, if you want to use like me the JAXB interfaces/classes model
( use <globalBindings generateValueClass="false"> in your external bindings
file or
<xs:annotation>
<xs:appinfo>
<jaxb:globalBindings generateValueClass="false">
</xs:appinfo>
</xs:annotation> in your XSD )
you cannot write anymore
CatalogType catalog= new CatalogType();
because CatalogType is now a generated interface, the implementation
classes are, by default, in the impl subpackage and are all suffixed by
Impl, so you should write
CatalogType catalog= new CatalogTypeImpl();
and so you inderstand that
CatalogType catalog=factory.createCatalogType();
works in both cases !! and is much cleaner ...
