How to read a client's File system

Question

Hi,
I use a web application where in the client can upload a directory to the server. Then the server should display all the files under that directory by fetching details from the client's disk.
how should this b done with java? Java file system does not allow this. If contents of a single file needs to be read, then it can be sent as multipart form data.
How to read or find out the files under a directory on the client machine?
Thnx in advance

It can be done using the File class used in Java. It can list out directories .
Several methods are available for inspecting an instance of the File class. Some of the important ones are:
Method                                                                                             Purpose
boolean exists()                                   does the file exist?
boolean isFile()                                    is it a file?
boolean isDirectory()                            � or a directory?
String[] list()                                       return the names of all files and directories in a directory
String getName()                                get the file or directory's name
String getPath()                                  get the file or directory's path
These methods are actually all we need in order to find all files and directories in a given directory--all the way down to the last leaves in the directory tree.
