How to populate the root/nodes of hierarchyviewer component in ADF without using datacontrols

Hi Guys,

I'm trying to put in a <dvt::hierarchyview> in my jsp page and moreover I don't want to bind it to any datacontrollers(The LOVs generated directly from the DBs). Is it possible to bind it to a method in a class which would be returning a collection object (list n all)??? How the linking can be done between the root and child nodes in that case?
Please suggest. It's an urgent requirement friends, expecting immediate response.

Thanks in advance.....
