and Hibernate

[Cosmin Stanciu <se...@yahoo.com>]

Hi! 
I have been trying for a week now to populate one <s:tree> with the data from a database table but with no luck . I would really apreciate some guidance in how to write the ShowDynamicTreeAction class that sends the date to the tree.

I'm using Hibernate DAO to receive the data from my database table and it looks like this.
Category: id, name, parent_category_id (from a a recursive 1:n relation to the same table using the id).
The Hibernate generated object (Category.java) has the fallowing fields: 
private Integer id;
private Category category;
private String name;
private Set categories = new HashSet(0);

In the CategoryDAO class I have all the methods needed to retreive data from the table:
- Category findById(int Id), List findById(int Id), List findParents() and I can add any needed method...

My struts.xml has a reference to the class showDynamicTreeAction:
        <action name="showDynamicTreeAction" class="struts2.ShowDynamicTreeAction">
            <result>/jsp/CategoryList.jsp</result>
        </action>

I'm sure that helping solving this issue would be of much interest for all those that intend to use s:tree in their application, as there no example or help regarding this matter on the internet.

Thanks a lot!
Cosmin

Is the documentation at
http://struts.apache.org/2.0.9/docs/tree.html out of
date? I haven't looked at it in quite awhile now.
