The Jakarta Commons Net project includes an ftp client library, which makes it easy to include ftp capabilities into your application.

You can do basic FTP using the Standard API:

Hi Joe and Ulf, as you mentioned, i could directly refer the file and download. Is it possible to log into ftp site and based on the folder name provided, can i browse and get the files in that folder?

For excample
ftp://user

ass@ftpsite.com/gopi/a.txt

i will log in using the URL - ftp://user

ass@ftpsite.com. will be possible to browse folders under the root and get 'a.txt'?

Thanks again

If you use the Jakarta Commons Net package Ulf mentioned, there's methods in the FTP client object to list the contents of a directory.
With the URL-based method, you simply request the directory rather than a particular file.
The convenient thing about the Net package is that they do the parsing of the directory information for you. With the URL-based method you get a text listing of the directory and you have to parse out the file names.

Did you read the Commons Net FAQ?

Q: Does FTPClient support FTP connections through an FTP proxy server?

A: Paul Buchanan answers this question here: [WWW] http://marc.theaimsgroup.com/?l=jakarta-commons-user&m=107877944806547&w=2

The summary is:

Since the Net project uses java.net.Socket under the covers, you have to set up the Socket settings. If the proxy you are using is a SOCKS4 or SOCKS5 proxy, you can set the following System Properties:

System.getProperties().put( "socksProxyPort", "1080");
System.getProperties().put( "socksProxyHost" ,"proxy.host.address");

From what I can tell, 1080 is the default port for SOCKS proxies. The following site documents many of the networking System Properties available:

Thanks!

I have read this link but our firewall, nat etc is on a sun solaris with an proxy server that does not support socks proxy. Only http and ftp
