Constructing JTree with object[ ] vs object graph

Question

I have data in a resultset that represents a parent-child relationship. there are fields that identify the parent as well as the position of the item
Now i want to display this information in a JTree.
The field format is something like this:
description parentid level1 level2 level3 level4... etc up to level7
the level{#} fields determine the position in the tree
im also looking at the examples here

im wondering if i need to implement my own treemodel or just create my object array and feed it to the JTree constructor
suggestions welcome

Hi,
I have study JAAS with J2EE for the last two months, don't know whether my ideas can help you. I believed JAAS was designed for java programmer who wanted to have security implement in there application but do not want to write the security themself. JAAS provided a robust system so that someone else can come alone to plug in the security module and security would be implemented.
Base on your problems, I think what you should do is to have what know as a security access level implement in your object. When you uses JAAS to verify username & password, you can get user's access level as well maybe from LDAP server attribute, store in your principal. So whenever you want to check whethere you're a editor or author.
You have to identify what is business logic and security logic access level is a business logic, therefore you will have to implement in your application tier. There is no perfect solution, but having these module will save you lots of coding and flexibility.
Cheers,
ps: Please correct me if my view are wrong.
