Struts - example of iterate using a hashtable (key,value)

Question

I am trying to create a dynamic menu system and each menu group
is storied within a single hashmap with the name of the menu as the key (e.g. "mainmenu", "adminmenu"). I am having problems understanding the documentation on how to pass the key to select the
right entry within the hashmap. I have read the following but find
it confusing. Could someone provide a detailed example?

Here's some code to show you what I am doing.
I will start out with how I am creating the List and the HashMap
    menuList = new ArrayList();
    sqlStatement = "select * from menu where admin = 'Y' ";
    // gets the menu items from the database and builds the menuList
    this.buildMenu( (DBResultSet)db.executeSQL( sqlStatement, args ) );
    // puts the menuList into a HashMap with a key of adminmenu
    //  NOTE: the menuList is actually a collection (list) of beans
    menuMap.setItem ("adminmenu", menuList );
    ...Here's my bean that stores I use to store the HashMap (menuMap).
import java.util.*;
public class MenuBO extends BaseBusinessObject
  private HashMap menuMap;
  public MenuBO()
    menuMap = new HashMap();
  public void setItem ( String menuType, List menuList )
    menuMap.put ( menuType, menuList);
  public List getItem( String menuType )
    return  (List)this.menuMap.get( menuType ) ;
  public HashMap getMenuMap ()
    return menuMap;
  public void removeItem ( String menuType)
    menuMap.remove( menuType);
}And here's my iterate which is not working. I want to single out the value that has a key of "adminmenu" and process that list of menu elements. This is easy to do with scriptlets but I am spending many hours trying to figure out Struts documentation - they need some real world examples if they want Struts to catch on...
<jsp:useBean id="menuMap" scope="session"
          class="com.benchdogs.webapp.beans.MenuBO"/>
        <logic:iterate id="mapEntry" name="menuMap" property="menuMap">
            <bean:write name="mapEntry" property="key"/>
        </logic:iterate>This example loops through the hashmap and displays the keys. I want to be able to process a specific value based on the key. The value is a List so I would need to do another iterate statement within the master iterate.
