Hi !
   I need to develop an application to display data in a tree structure very much similar to how Windows Explorer displays the tree on the left side.
   I know this can be done using Applets but I cannot use applets for now. I need to use plain JSPs and Servlets.

   If anybody has any experience in developing anything like this or any free third party tool or any pointer that can lead me to a soultion for this problem, please do let me know..

Any help is greatly appreciated.

Thanks in advance,
