In my project, i want to use tree componet, and who can give me some example about it? thanks
You have an example on Richfaces demo site with the source.
Check out http://scar.rivetlogic.com. I have used tree and if that is what you want you can get source from https://svn.rivetlogic.com/repos/rivets/app/scar/scar/trunk/
Hope that helps.
