i want to ask how to make generate menumodel from database using recursive function.
i already make this class but it's not working. please help me,i already find and trying for a week .thanks
public class MenuDAOImpl extends ManagerBase<MenuMaster> implements MenuDAO {
private List<MenuMaster> list;
private List<MenuData> datas;
#Override
public MenuModel getMenu() {
MenuModel model = new DefaultMenuModel();
String[] orders = new String[]{"id"};
try {
list = getBySQLQuery("PARENT_MENU_ID=0", orders, 1000);
for (MenuMaster menuMaster : list) {
menuChild(menuMaster);
}
} catch (Exception e) {
}
return model;
// throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods, choose Tools | Templates.
}
private List<MenuData> menuChild(MenuMaster master) {
List<MenuData> listChild = new ArrayList<MenuData>();
String[] orders = new String[]{"id"};
try {
MenuData data = new MenuData();
data.mm = master;
data.mms = getBySQLQuery("PARENT_MENU_ID=" + master.getParentMenuId(), orders, 1000);
listChild.add(data);
} catch (Exception e) {
}
return listChild;
}
public class MenuData {
private MenuMaster mm;
private List<MenuMaster> mms;
public MenuData() {
}
public MenuMaster getMm() {
return mm;
}
public void setMm(MenuMaster mm) {
this.mm = mm;
}
public List<MenuMaster> getMms() {
return mms;
}
public void setMms(List<MenuMaster> mms) {
this.mms = mms;
}
}
}

Here's some code I had lying around, I create the menumodel by appending submenus and menuitems to his getChildren() property
private MenuModel model;
public MenuModel getModel() {
if(model != null) return model;
model = new DefaultMenuModel();
addDynamicMenus();
return model;
}
private void addDynamicMenus(){
if(modules == null){
modules = service.getModulesByUserLogin(loginBean.getUsername());
}
Submenu currfather = null;
for(SpFeModuleForUser s : modules){
if(currfather == null || (!currfather.getId().equals("menu_" + s.getModuleID()))){
currfather = new Submenu();
currfather.setLabel(Modules.getSingleton().getString(s.getModuleName()));
currfather.setId("menu_"+s.getModuleID());
model.addSubmenu(currfather);
}
MenuItem mi = new MenuItem();
mi.setValue(Modules.getSingleton().getString(s.getNAME()));
mi.setId("_" + s.getKey());
mi.setTarget("_self");
mi.setTitle(Modules.getSingleton().getString(s.getNAME() + "_Description"));
mi.setAjax(false);
mi.setUrl(url);
// Add parameters
UIParameter param = new UIParameter();
param.setName("moduleid");
param.setValue(s.getKey());
mi.getChildren().add(param);
mi.setProcess("#all");
currfather.getChildren().add(mi);
}
}
