FTP proxy will impact all WLS server

Question

Hi everybody.
I try to use proxy to FTP. But when I set the socksProxyPort, socksProxyHost. This
will impact all WLS instance. It seems due to use System.getProperties().put().
How can I use the local setting for proxy.
My code looks like this:
System.getProperties().put( "socksProxyPort", "1080");
System.getProperties().put( "socksProxyHost" ,"ftp-proxy");
Authenticator.setDefault(
new Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication("p_ebo_ldt_ftp1","opcftp123".toCharArray());
);

If what Tim has suggested doesn't help, you could try to use a Proxy Automatic Configuration file. It may help forward certain protocols to use the proxy. You can find more information about PAC files here: http://en.wikipedia.org/wiki/Proxy_auto-config
Here is an example we use:
function FindProxyForURL(url, host) {
// If IP address is internal or hostname resolves to internal IP, send direct.
var resolved_ip = dnsResolve(host);
if (isInNet(resolved_ip, "10.1.0.0", "255.255.0.0"))
return "DIRECT";
else
return "PROXY 127.0.0.2:80";
I've changed the IP address values to protect the privacy of where I am employed
