How do you read a directory structure from within an applet?

[Peter Smith]

If I have an applet running on a web page, how can I get this applet to read

a directory (and then subsequent dirs) on the server, and then read the filenames

and then display the filenames (or whatever)??


is this possible?

Hello Peter,


Yes,you can do reading a directory.this can be done using

recursive calls(possible there are other solutions too!).i tried to read

dirs and files for my c:. it worked and the simple code is:

File f = new File("C:");

String[] flist;

flist = f.list();

the flist string array returns all the files and dirs of c:.next the dirs

must be searched again and this will continue till there are no more dirs

to search.hope this provides a start.ur feedback will be appreciated.


best wishes

hmmm...


can this be done in an applet?


I have found some code to read a text file from the orginating host...but how can I

read a directory???????


try{

URL url = new URL("http://somewhere.com/test.txt");

// or URL url = new URL( getDocumentBase(), filename);

BufferedReader in = new BufferedReader(new InputStreamReader(url.openStream() ) );

String s = in.readLine(); //read till you get a null line.

} catch(MalformedURLException e){

System.out.println("URLException:"+e);

} catch(IOException e){

System.out.println("IOException:"+e);

}

Not without help from the server.


Scenario 1: You could set up the web server to display the directory listing as

a web page. Works only when you don't have any default page in that directory.

You could read the webpage and parse it. Not recommended.


Scenario 2: Install a CGI (or CGI like) script at the server. This script should

serve up the content of the directory. You'd again have to load the page using

HTTP and parse the result. Recommended.
