ftp

how can i incoroporate ftp functions into my java code?

I tried searching at sun but found nothing

i would use the basic functions rather then using a set of functions someone else has developed

cheers

What kind of functions do you want? Downloading a file from an ftp server isn't too complicated.

First create a URL object and give the protocol, host and a filename (you could use a different constructor if you wish):
URL url = new URL("ftp", "ftp.foo.com", "/pub/file.txt");

Now you can connect to the server:
URLConnection conn = url.openConnection();
conn.connect();

To read data from the file, get an input stream:
InputStream in = conn.getInputStream();

This next bit will print the contents to standard output (only good if it's a plain text file):
BufferedReader br = new BufferedReader(new InputStreamReader(in));
String line;
while ((line = br.readLine()) != null) {
System.out.println(line);
}

As ross has pointed out downloading from an FTP server isn't difficult at all. Same goes for uploading. Unfortunately if you want more than that you need to find an FTP library there are several available (shameless plug: including our own free library).
