Nested Bean Problem

[pr...@seepz.tcs.co.in]

Hi,

I have a problem handling nested beans..
For example...
I have a userBean as given below
     private int userID;
     private String lastName;
     private String firstName;
     private ArrayList roleUser;
Where the last field Arraylist is the arraylist of the objects of the bean
called roleUserBean.

Again the roleUserBean has the following properties.
     private int roleid;
     private String desc;
     private String name;
     private ArrayList menuComponent;
The last property menuComponent is the arrayList of objects of the bean
called menuComponentBean.

Now the menuComponentBean contains
     private int menuID;
     private String menuName;
     private String description;


I have put the userBean in the session scope. But I don't know how can I
drill down from the userBean to one of the menuName. I want to display the
menu dynamically getting the menu items from the userBean.
How can I use the <logic:iterate> tag to get all the menuNames from the
userBean?  Or is there any other efficient way in which I can get the
menuNames to be displayed in my JSP(view) part.

Thanks in advance.
Prashant M Desai.

<logic:iterate name="userBean" scope="session" id="userbean">
    <nested:write property="userID"/>
    <nested:write property="lastName"/>
    <nested:write property="firstName"/>
    <nested:iterate property="roleUser" id="roleuser">
        <nested:write property="roleid"/>
        <nested:write property="desc"/>
        <nested:write property="name"/>
        <nested:iterate property="menuComponent" id="menucomp">
            <nested:write property="menuID"/>
            <nested:write property="menuName"/>
            <nested:write property="description"/>
        </nested:iterate>
    </nested:iterate>
