In trying to get an InputStream on a URL connection (on the base directory),
I tried two types of strings and each threw a different exception.

1.
url = new URL("ftp://" + ftpServerName + "/");
con = url.openConnection();
System.out.println("1");
  
in = new BufferedReader (new InputStreamReader(con.getInputStream()) );
    ***************exception here gets thrown****************
           
            FtpProtocolException
            'RETR' : 500 command not understood
            
2. url = new URL("ftp://" + ftpServerName);
con = url.openConnection();
System.out.println("1");
  
in = new BufferedReader (new InputStreamReader(con.getInputStream()) );
   **************exception here gets thrown*************

            StringOutOfBoundsException
            String index out of range:0
