From source file:uk.ac.manchester.cs.datadesc.validator.utils.UrlReader.java

private InputStream getInputStream(FTPClient ftp) throws VoidValidatorException {
    try {/*from   ww w. j a  v  a  2s  .  co m*/
        // in theory this should not be necessary as servers should default to ASCII
        // but they don't all do so - see NET-500
        ftp.setFileType(FTP.ASCII_FILE_TYPE);
        ftp.enterLocalPassiveMode();
