You can use HttpClient for the control. Portion of the FTP protocol, but you would need to set up a separate connection on the data port. If you go with passv ftp, you could open another connection and then do your own data management.
Sun's URL connection support FTP protocol and takes care of the PASSV handshake automatically. -----Original Message----- From: Oleg Kalnichevski [mailto:[EMAIL PROTECTED] Sent: Tuesday, December 20, 2005 9:25 AM To: [email protected] Subject: Re: ftp via http On Tue, Dec 20, 2005 at 03:14:39PM +0100, Roland Weber wrote: > Hello Harm, > > FTP and HTTP are completely different protocols. > You can not use HttpClient to access an FTP server. > > You may be able to tunnel FTP via an HTTP proxy, > but HttpClient will only help you with the tunnelling. > You still have to implement FTP yourself, including > the authentication against the FTP server. > > cheers, > Roland > Roland, Actually some web proxies are capable of executing FTP requests on the client's behalf.
