Hi Andrei,

   fullName is a basic mapping so you'll need:

            <basic name="fullName">
                <column name="FULL_NAME"/>
            </basic>

    It's defaulting to Basic when you use annotations. And in Java you
have the field declaration to attach the @Column to, but in XML you need
to provide the <basic> element so you have some context for the nested
the <column> element.
