listing files at the FTP

hi, i've just begun the java. And i want to file information (name, date or md5) on FTP server. I succeed to upload to FTP server.
but, i can't download and get file information.
i use sun.net.ftp.FtpClient library for upload file.
how i can list file and get information (date, name) ?

Thanks.

you can use the method list(), that returns a TelnetInputStream.
You could print the return e.g. with the Scanner class

Code:

---

                Scanner sc = new Scanner(ftpClient.list());
                while(sc.hasNextLine()){
                        System.out.println(sc.nextLine());
                }

you will receive the date, size, name etc.
with cd(String s) you can change the directory
with get(String s) you will get a TelnetInputStream too and you can download the file

sun.net.ftp.FtpClient

Does this class still exist? Back when it used to the advice commonly given about using *any* of the sun. packages was: "Don't. They aren't portable and they aren't supported."

You might want to consider Apache's FTP client which is part of Apache Commons (Commons Net - Jakarta Commons Net) or some other Java ftp client.

the codes are follows. werite "abc" on terminal and nothing anything.
i check on filezilla and i see uploaded the file , but not listed in the directory.

Code:

---

public void uploadDumpFiles2Server(){
        String server="ftp.domain.tr";
        String user="username";
        String password="password";
        String path="/httpdocs";
String filename="user.props";
        try {
            FtpClient ftpClient=new FtpClient();
            ftpClient.openServer(server);
            ftpClient.login(user, password);
            if (path.length()!=0) ftpClient.cd(path);
            ftpClient.binary();
            TelnetOutputStream os=ftpClient.put(filename);
           
            File file_in=new File(filename);
            FileInputStream is=new FileInputStream(file_in);
            byte[] bytes=new byte[1024];
            int c;
            while ((c=is.read(bytes))!=-1){
            os.write(bytes,0,c);}
            is.close();
          Scanner sc = new Scanner(ftpClient.list());
                while(sc.hasNextLine()){
                        System.out.println(sc.nextLine());
                }
            os.close();
            ftpClient.closeServer();
        } catch (IOException ex) {;
            System.out.println(ex.toString());
        }

mhm..I have tested your posted code and it works fine when I put the line os.close(); before the line Scanner sc = new Scanner(ftpClient.list());

But I agree with pbrockway2 you should not use the sun packages if possible(see:FAQ - Sun Packages)

Thanks. But 've a problem. download apache coomon file.
but, how to i import this library ?
I tried something but could not succeed.

ok. i solved. Thanks for everything.
