Hibernate - Herança Simples

#1

pessoal,

estou tentando fazer uma herança pelo Hibernate onde as classes Funcionario e Cliente descendem da classe Usuario.

Usuario.hbm.xml

#             <key column="ID_USUARIO"/>  
#             <one-to-many class="com.domain.Endereco"/>  
#          </set>          
#            
#          <discriminator

#       </subclass>   
#                  
#     </class>  
# </hibernate-mapping>

Estou obtendo o seguinte erro:
