class SubMenu
{
@OneToMany(targetEntity=AbstractMenuItem.class,
cascade=CascadeType.MERGE,fetch=FetchType.EAGER)
@IndexColumn(name="position")
@JoinTable(name="relation_submenu_menuitem",
joinColumns={@JoinColumn(name="sub_menu_reference")},
inverseJoinColumns={@JoinColumn(name="menu_item_reference")})
public List<MenuItem> getMenuItems()
{
return menuItems;
}
...
}
My expected primary key of relation_submenu_menuitem is primary key{sub_menu_reference,menu_item_reference,position},but actual primary key is primary key{sub_menu_reference,position}.Only the combination of three columns can be primary key in my application.Can anyone help.

Thanks,

i have a problem with @ManyToMany too.
class User
{
@ManyToMany(targetEntity=Card.class,fetch=FetchType.EAGER)
@JoinTable(name="relation_user_card",
joinColumns={@JoinColumn(name="user_reference")},
inverseJoinColumns={@JoinColumn(name="card_reference")})
public Set<Card> getCards()
{
return _cards;
}
...
}

class Card
{
@ManyToMany(targetEntity=User.class,fetch=FetchType.EAGER,mappedBy="cards")
public Set<User> getOwners()
{
return _owners;
}
...
}

when i invoke:
user.getCards().remove(card);
userDao.update(user);

relation_user_card relation table will not be updated to delete the relation between the user and that card(i checked generated sql,no sql for that).Only when i invoke user.getCards().clear(),then all relation for that user will be deleted from relation_user_card table.why does user not maintain the relation for the first situation?
