how do i go about this

Requirement!

select a folder! on selecting the folder,all the files must be listed(preferably in a checkgroup,with all files checked by default).i will be able to choose the files i need to process.once chosen i need to extract information from each of these files and transfer data to a new file.

i tried using the fileUpload control,but i can select only files not a folder!also there seems to be no way of getting a file's fully qualified pathname,once i select a file using fileupload.is it possible to use swing's JFileChooser somehow within webdynpro,or is something similar available?
