Demonstrates connecting through a traditional FTP application proxy or firewall using ProxyHostname, ProxyPort, ProxyUsername, ProxyPassword, and ProxyMethod.

// Important: Don't forget to include the call to System.loadLibrary
// as shown at the bottom of this code sample.

    //  The proxy's own credentials (distinct from the FTP server login).
    ftp.put_ProxyUsername("myProxyLogin");
