Re: Hiding an ftp URL
Might be helpful to take a look at the difference between protocols FTP and HTTP http://www.webopedia.com/DidYouKnow/Internet/2002/FTP_HTTP.asp The answer is no You don't need to visually display an ftp address in your address bar to initiate an FTP session if you follow the instructions from my previous email you will see how a FTP transfer can happen almost in background (more akin to spawned daemon) HTH, Martin Gainty - Original Message - From: "Susan Hoddinott" <[EMAIL PROTECTED]> To: "Tomcat Users List" <[EMAIL PROTECTED]> Sent: Saturday, December 11, 2004 3:34 AM Subject: Re: Hiding an ftp URL > Hi, > > I was attempting to use an http ftp command as in the former case.

Re: Hiding an ftp URL
Hi, I was attempting to use an http ftp command as in the former case. I thought there might be some way of mapping it to some sort of a synonym like used for servlets in the web.xml file?

Re: Hiding an ftp URL
Without knowing what you are transferring or if you are transferring in Passive or Active or if there are Proxies setup you can use Sun's FTPClient sun.net.ftp.FtpClient Knowing these limitations a.. the FtpClient class is unsupported by Sun (even though it works, they could modify or remove it at will in later versions) b.. it doesn't support an automatic way to parse directory listings, which makes it quite difficult to list the files and subdirectories on a server Here is an example http://www.nsftools.com/tips/JavaFtp.htm Viel Gluck, Martin - Original Message - From: Susan Hoddinott To: Tomcat Users List Sent: Friday, December 10, 2004 12:36 AM Subject: Hiding an ftp URL Hello, I am wondering what the best way to avoid display of an ftp URL is when redirecting to an ftp location.

RE: Hiding an ftp URL
Hi, You could also try forwarding (RequestDispatcher) from your servlet to the FTP resource, rather than redirecting. The servlet's address will remain in the browser's address bar.

Are you redirecting the user's browser to that location, or are you wanting to obtain content from that location to send to the user's browser via a servlet running under (say) Tomcat? If you want to do the former, it's not possible as the browser's address bar / properties window will show the FTP location. If the latter, one simple approach would be to write a servlet that opened a ReadStream on the FTP resource and repeatedly read from that and wrote to the servlet's output stream; I have no doubt there would be better and more standard ways if I was more familiar with the servlet spec! - Peter - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
