Hi all,
I have been thinking on how to use castor JDO for my problem. I
have
Been asking same question before, and got answer, but the problem has
changed slightly.
I m working on existing database where following tables are present
Menu Group
ID Name
Nested_Menu
PARENT_MENU CHILD_MENU
Menu Items
MENU_ITEM_ID MENU_ITEM_NAME MENU_GROUP
THE meaning is the following. I have a set of menu groups (nodes) and
set of
Menu items (leafs).
The Nested menu table lists relationships between menu group, coz one
menu group can be part of another menu group.
A Menu Group can have either as a children a Menu Groups or Menu Items
I have little trouble in figuring out how to write classes to map my
tables
To objects.
I thought of writing following class
Public class Menu {
setId()
setName()
setMenuItems()
setChildMenus()
getId()
getName()
getChildMenus()
getMenuItems()
}
public class MenuItem {
setId()
setName()
getId()
getName()
}
But I don't know how to write the proper mapping.xml for menu class,
since
For retrieving child menus I have to look at nested_menu table...
Anyone can help?
Thanx and regards
marco
