Apache Commons FTPClient.listFiles

Question

I am using org.apache.commons.net.ftp.FTPClient in one of my applications to work with a FTP server. I am able to connect, login, pwd

Answer 1

I had to same problem and it turned out to be that it couldn't parse what the server was returning for a file listing. I this line after connecting to the ftp server ftpClient.setParserFactory(new MyFTPFileEntryParserFactory());

public class MyFTPFileEntryParserFactory implements FTPFileEntryParserFactory {
private final static FTPFileEntryParser parser = new UnixFTPEntryParser() {
    @Override public FTPFile parseFTPEntry(String entry) {
        FTPFile ftpFile = new FTPFile();
        ftpFile.setTimestamp(getCalendar(entry));
        ftpFile.setSize(get(entry));
        ftpFile.setName(getName(entry));
        return ftpFile;
    }
};

@Override public FTPFileEntryParser createFileEntryParser(FTPClientConfig config) throws ParserInitializationException {
    return parser;
}

@Override public FTPFileEntryParser createFileEntryParser(String key) throws ParserInitializationException {
    return parser;
}

}
