Retrieving a directory listing from JSP

Hi all,
simply put is this possible from a specific object (ie Directory or File Object) from within JSP? I realize there are ways of doing it with Runtime object and "ls" / "dir", but I was wondering if there was any "cleaner" way than parsing the returning stream from these processes. Thanks in advance!

I would have thought you could do this from JSP exactly the same way as you can from a Java App. Create a new java.io.File object (new File (path)), call the listFiles method and use the returned array of files to print out the names (through the use of File.getPath() or such like.
Not sure on the directories that you will be able to see. Give it a go and see.

You can definately do this is jsp, the way Sam has described. I have done it.

Sure, you can do this, but the directories that you will see will be from the server that the JSP is running. You wont be able to see the client's directory structure since the JSP is compiled and executed on the server, so dont waste your time if this is your intention.
