Is it possible to write a program in java that can do a FTP file transfer

[Todd M Bush]

Sure is. I'm working on one right now. There are a few examples out there as well.

Could some post some examples for ftping files over to an IP address?
Iam thinking of using the URL class with protocol=ftp. Is this the way to do it?
Thanks,
Savithri

Is there a way to run unix shell script through Java?

[Carl Trusiak]

Yes there is. You have to understand a little about the URL it is expecting.
ftp://username :[email protected]/full/path/to/file/filename;type=x
type for getInputStream can be 'd' for directory listing, 'a' for Ascii down load and 'i' for Binary download.
type for getOuputStream can be 'a' for ascii upload and 'i' for binary upload.
So, to put a text file you can use code similar to the following

  URL url = new URL("ftp://username :[e-mail]/full/path/to/file/somefile.txt;type=a");
  BufferedReader br = new BufferedReader(new FileReader(new File("somefile.txt")));
  URLConnection urlConn = url.openConnection();
  PrintWriter pw = new PrintWriter(new OutputStreamWriter(urlCon.getOuputStream()));
  String line = "";
  while((line = br.readLine()) != null)
  {
     pw.println(line);
  }
  br.close();
  pw.flush();
  pw.close();

Hope This Helps

Carl,
I appreciate your help here, but what is "/full/path/to/file/filename"?? Did you mean "filedirectory/filename" ??
I am pretty much doing the same thing, but I get an exception on the getOutputStream() statement. UnknownServiceException" - This service is not supported by the protocol.
Only difference is - I am not setting type='a'. I am going to try that next.
Any ideas??
