Usage

From source file:de.idos.updates.lookup.FtpLookup.java

private Version findLatestVersion() throws IOException {
    FTPClient ftpClient = new FTPClient();
    ftpClient.connect(inetAddress);/*from  ww  w.  j ava  2  s  .  c  o  m*/
    ftpClient.enterLocalPassiveMode();

    if (login != null) {
        ftpClient.login(login, null);
    }

    if (workingDir != null) {
        ftpClient.changeWorkingDirectory(workingDir);
    }

    FTPFile[] availableVersionsDirs = ftpClient.listDirectories();
    List<String> strings = new ArrayList<String>();
    for (FTPFile ftpFile : availableVersionsDirs) {
        strings.add(ftpFile.getName());
    }

    List<Version> versions = new VersionFactory().createVersionsFromStrings(strings);
    return new VersionFinder().findLatestVersion(versions);
