parent/child structure display using jsp

[Madhu Bhat]

hello,
I am developing the project using struts,spring,hibernate,jsp. I have a problem in displaying the tree structure of categories

abc--parent category(parent)
def--sub category(child)
ghi

jkl
lmn
op
rst

this is the display structure that i should get.

I have a table name Categoty where primarykey is id and foreignkey is parentCategory which is relating to the same table.

table structure :
ismoderated, langid, type, modifiedon, orgid, parentid, modifiedby, status, createdby, name, createdon, id

Is it just to "show" as a tree view and of course admin as parent/child structure? If so, I have 2 classes that make it work pretty fine.
