@Giuggiola

     @OneToMany(mappedBy="parlamentare",
    		 targetEntity = Range2.class)
    		// cascade = CascadeType.ALL, 
    		// orphanRemoval = true,
    		// fetch=FetchType.EAGER)//fetch=FetchType.EAGER)//cascade = CascadeType.ALL, orphanRemoval = true)//targetEntity = Range2.class,fetch=FetchType.EAGER)
 	private List<Range2<LocalDate>> periodo_carica = new ArrayList<Range2<LocalDate>>();

This mapping you did tells Hibernate that Range2 is an entity, and the definition of the join columns is located in an attribute named parlamentare within Range2 which I guess is not what you want?

You will probably want to map this as @ElementCollection like this:

@ElementCollection
@CollectionTable(name = "periods")
List<Range2<LocalDate>> periodo_carica = new ArrayList<Range2<LocalDate>>();

In fact no, thanks!!!
