Subject Problem proxy with commons-net
Date Tue, 20 Nov 2007 09:29:56 GMT
Hello,

I tried to create a connexion on a remote server, 
I have to use a proxy (squid) to access to the remote server.

here a simple code:

System.setProperty("socksProxyHost", ipProxy);
System.setProperty("socksProxyPort", port);

Authenticator.setDefault(new MyAuthenticator());
FTPClient client = new FTPClient();
try {
        System.out.println("connect...");
        client.connect("ca.expasy.org", 21);
        System.out.println("login...");
        client.login("anonymous", "anonymous@nowhere.com");
        } catch (IOException e) {
            e.printStackTrace();
            System.err.println(e.getLocalizedMessage());
        }

public class MyAuthenticator extends Authenticator {
    protected PasswordAuthentication getPasswordAuthentication() {
        System.out.println("*** getPasswordAuthentication *** ");
        return new PasswordAuthentication( "login","password" );
    }
}

the result is :
Test:
     [java] connect...

I tried to set a lot of system properties 
(socksProxySet,ftpProxySet,...,socks.proxyHost,....) but nothing works...
someone have any idea?
