将JSF树与文件夹目录同步

Question

I have to keep the user uploaded files under a directory by category. The application directory have to show this directory as tree on web page. I am using JSF 2.0 + Richfaces 4.0. I have to make programmatically to show directories structure with tree on web page. Any one provide the API or lib to get recursive directory structure from my root level directory?
