and the Profile.class is:

@Entity
  | @Table(name = "BAS_ROLE", schema = "UTIL")
  | public class Profile extends Pojo implements Serializable {
  | 
  |     @Column(name = "ID_ROLE")
  |     @Id
  |     @GeneratedValue(strategy = GenerationType.AUTO)
  |     @NotNull
  |     private long id;
  | 
  |     @NotNull
  |     private String profile;
  | 
  |     private String description;
  | 
  |     @ManyToOne
  |     @JoinColumn(name = "ID_LICENCA")
  |     private License license;
  | 
  |     private boolean screenProfile;
  | 
  |     @ManyToMany
  |     @JoinTable(name = "CONF_ROLESYSTEM", schema = "UTIL", 
  |                joinColumns = {@JoinColumn(name = "ID_ROLE")}, 
  |                inverseJoinColumns = {@JoinColumn(name = "ID_SYSTEM")})
  |     private List<Sistem> sistems;
  |     
  |     @ManyToMany(mappedBy = "profiles")
  |     private List<User> users = new ArrayList<User>();
  | 
  |   //GETTERS and SETTERS
