URL class is not working in Java 1.4. However works in Java 1.3

Question

I have a Java program which uses URL classes through FTP connection to open any files. It works fine in Java 1.3 version. However the same program fails with
java.io.FileNotFoundException: at sun.net.www.protocol.ftp.FtpURLConnection.getInputStream
when using Java 1.4 version.
Here is the part of source code.
try
URL url ;
url = new URL("ftp://"); // I have not given the full connect string here.
URLConnection connection = url.openConnection();
BufferedReader in = new BufferedReader(new InputStreamReader(connection.getInputStream()));
String inputLine;
while ((inputLine = in.readLine()) != null)
System.out.println(inputLine) ;
in.close();
catch(Exception e)
System.out.println("Error occured " + e.getMessage());
Anyone has ideas about what is going wrong and how to correct that. I appreciate your reply.
Thanks
