How to make a JTree show restricted file hiearchies

I need to make a jtree display disabled/hidden file hiarchies. any idea how to do this?

Um..what is a disabled file?
The java.io.File already has a convenient isHidden() method.

Pseudo code
1) Start with a root
2) Iteratively extract list of all children under that root
3) Define parent child relationships by creating tree nodes from the files
4) Create a JTree from the nodes and display it

In such scenarios, recursion is always helpful and elegant.
The java.io.File is your friend here.
Check out File#listRoots(), File#listFiles(), File#isDirectory(), File#isHidden()

In case you want to know about tree creation, check this out http://java.sun.com/docs/books/tutorial/uiswing/components/tree.html

disabled = not allowed access because admin doesnt allow you to.

Then you can't read those period. The operating system is blocking your access, and there is nothing Java can do about that.

You shouldn't even try. If your system admins blocked those folders then they most likely have had a very good reason to do so. If they haven't, ask them to give you permission.

Note: I'm working very closely with our system admin so I'm biased.

Is your question about retrieving files not accessible to you or is it about display the file structure as a tree?

both. i want to show the files and be able to open/retrieve them.

i am doing this for school. i need to acess some files, copy them and such.

Have you tried asking the sysadmins if you can get access to them? If they say no, talk to your professor. If he doesn't back you up you probably don't really need them.

yeah... that wont hapen...

but i just realized i can use linux to acess anything i want to that is on the hard drive..... still working on the network
